Dry, Cracked Heels: Causes and Treatments April 17, 2013

Dry skin on the heels, even cracked skin, is a fairly common problem that can be treated at home.  Be sure to give your feet some extra TLC year round, not just in the summer when you are wearing sandals.

Causes

So just what causes dry, cracked skin on our heels and feet?  There are more than a few causes for this condition, but first let’s remember everything our feet do for us on a daily basis.  The Skin Inc. article Sole Searching by Vicki Malo gives great overview on this issue:

The amount of pressure exerted on the feet gives a good indication that the skin on the soles must be very different than on the rest of the body.

The skin of the soles

The skin of the epidermis on the soles of the feet is much thicker; up to 1.4 mm and comprised of five distinct layers. It has to be thicker to withstand the amount of stress and pressure placed on the soles with every step. There’s more: The skin on the soles of the feet has an additional layer in the epidermis, and the skin cells are packed together in a strong, congruent membrane. The skin on the bottom of the feet also has four times more sweat glands, but does not have hair or sebaceous glands. Due to these functional features of the skin on the soles of the feet, it does not respond as readily to typical skin care techniques practiced elsewhere on the body.

The outermost layer of the epidermis, known as the stratum corneum, is crucial to the skin barrier. Made up of overlapping layers of cells, the stratum corneum keeps vital nutrients in, and damaging substances and elements out. Healthy skin keeps in moisture and protects against the entry of bacteria, fungus or viruses. Unhealthy or dry skin creates a portal of entry, leaving the skin traumatized and unable to perform its job of protection.

Lifestyle and foot issues

So why do you see so many clients with dry skin on their feet? A lot of the reason has to do with lifestyle. Today’s is a fast-paced, high-stress, super-sized lifestyle. Lack of exercise, and a diet high in sugars and simple carbohydrates can lead to a breakdown in the circulation of the lower limbs and increased incidences of diabetes. Lifestyle is the greatest contributor to developing chronic venous insufficiencies (CVI). Venous insufficiencies lead to a disruption in the function of the skin, breaking it down at an intercellular level. There are no capillaries in the epidermis; however, the skin is nourished by diffusion from the capillaries in the underlying dermis. If the capillaries are compromised, proper blood supply (nourishment) cannot be provided to the epidermis of the skin. Impaired elimination of metabolic waste due to CVI impairs the sweat glands, diminishing sweat production on the bottom of the feet. The tissue disturbances further cause a breakdown of the lipids, which are responsible for holding the cells together. The breakdown of the lipids causes the hydrolipid film to break down, leading to transdermal water loss. The skin loses elasticity and has less potential for regeneration. The intercellular water loss compromises the integrity of the skin leading to micro lesions, such as dry skin. Micro lesions are a portal of entry and can cause skin issues, such as athlete’s foot.

There are many other reasons that one can suffer from dry heels and feet such as cold weather, indoor heating, improper foot care, and standing on your feet all day.  There are even specific Ayurvedia explanations for dry and cracked heels:

Painful, cracked and dry heels is a predominant cosmetic problem and has been termed as Padadari in Ayurveda and has been explained inKshudra Rogas in Sushruta Samhita. There are innumerable remedies for cracked foot in Ayurveda and let’s have a look at the promising Ayurvedic essential oils for healing heel fissures.

Causes for cracks or fissures: Human foot is the powerful part of the body helping one to withstand all severe climatic conditions and roam around, yet it is this part of the body that is often neglected. Cracks on foot have no age limit and it can affect anyone for that matter irrelevant of the sex, color and origin. The major causes for cracks or heel fissures are:

  • Cracks are occupational especially for farmers and other people who are involved in laborious tasks that demand standing always, which lead to huge pressure on the foot forcing it to develop cracks.
  • Prolonged standing on hard floor and this is the reason why most of the homemakers develop cracks.
  • Dry, dull and lifeless skin that lacks moisture, especially during winter has the tendency to develop cracks.
  • Uncomfortable, not so fitting or open back footwear compels pressure on the foot, while widening and deepening the cracks.
  • Obesity or excess accumulation of fat and deficiency of essential nutrients like vitamins and minerals.
  • Dry, hot, humid and tropical climatic conditions make your feet dull, dry and hard paving way to develop cracks.
  • Aging and skin conditions like psoriasis, eczema, athlete’s foot etc.
  • High exposure of feet to dust, dirt, germs and other harmful organisms leading to infection in the foot.
  • Excess sweating of feet or other causal illnesses like thyroid and diabetes can also cause cracks on the foot.

Symptoms: Cracks generally appear on the external or outer walls of the heels, when it is thick and dry. The symptoms of cracked foot are dry, itchy and painful heels with flaky and red patches and partition of skin looking like root hairs. When left unnoticed, fissures may start bleeding with excruciating pain and might even lead to developing Calluses, Cellulites, and Lymphangitis etc. Anyone with cracked feet will have greater discomfort while walking and the cracks can act as a dangerous channel for bacteria, virus, fungi and other harmful organisms to enter into the body and complicate the situation.

Treatment Options

Now that we know the cause of dry and cracked heels what about the cure?

If you simply suffer from dry skin on your heels and feet you need to use a moisturizer with gentle acids in it in order to exfoliate and hydrate your feet.  Apply nightly after soaking your feet or taking a shower.  You can even wear cotton socks during the night if you want to in order to help the moisturizer penetrate deeper into your feet.

For very rough feet you can purchase a callous remover lotion or gel that is applied to the feet for about five to ten minutes.  After that time has elapsed file the skin gently with a pumice stone or foot file.  Finish with a moisturizer.

If your feet are cracked you need to use a product formulated for such a condition so that your skin can heal.

Bottom Line:  Though dry and cracked heels are an unpleasant phenomena this is a common skin condition that can be treated at home.  The key to proper treatment is finding the right product for you and using it daily.

Product Review: Dr. Spiller Pure Skincare Solutions February 20, 2013

Alpenrausch Organic

Months and months ago I was contacted by Melissa from Dr. Spiller skincare products asking me if I would be interested in trying some of the products from their organic line.  Even though I was in the process of moving back to Israel Melissa still graciously mailed all the products to my new home.  Not only that I also received full size products and an entire product brochure with ingredient breakdown.  I was impressed!  (Truth be told though I have been writing this blog for a little over three years I have very rarely received free products to try.  If I am contacted about receiving free products I always let the person know that I can’t guarantee that I will review their product, and if I do review the product I can’t guarantee it will be a positive review)

Before I get to my product review let me be very upfront about a few things – I see no reason to purchase organic skincare or beauty products as opposed to “conventional” products, I have no problem with parabens in skincare products (truth be told the Dr. Spiller line doesn’t talk about parabens, but I thought I would just throw that out there anyhow since the topic of organic skincare and parabens usually go hand in hand), and I don’t buy into the organic or natural skincare products are better for you nonsense.  (You can read more here and here for my opinions about these topics)  I am more interested in the feel, smell, and above all efficiency of a skincare product.  Does the product do what it says it will?  Yet in regards to the organic claim I was happy to see that Dr. Spiller did not just slap that label on their products without being able to back it up.  It turns out that their products meet strict standards for organic skincare products.  The fact that the products are full of natural ingredients is heavily promoted by the company, but in my view the proof is in the pudding.  If the product doesn’t feel good or make your skin look good then who cares what it has in it.

Here are the products that Melissa sent me to try:

First off take a look at the product information on the website.  Very thorough!  Not only is there a detailed explanation given for each of the main ingredients the product’s pH is stated along with the amount of lipids in the product and the base ingredient are listed as well.  I am all for as much consumer transparency as possible in skincare products so I was happy to see how much information was provided on the website.

After receiving the products I realized that some of them were not ideal for my very oily, acne prone skin, but I tried everything anyhow for the sake of this review.  After trying everything at least once I held onto the cleanser and passed the rest of the products along to my friend Vanessa.  I chose Vanessa as my tester because she has sensitive skin and has had numerous reactions to skincare products in the past.  Since this line is supposed to be good for sensitive skin I thought Vanessa would be the ideal candidate to try out the products.  So what was the verdict in regards to Vanessa’s sensitive skin and these products?  Vanessa experienced no irritation or side effects from using these products so indeed it seems that they really are ideal for those with sensitive or sensitized skin.

As I wrote above I kept the foaming cleanser for myself since I use a mild cleanser daily.  I liked that the cleanser came out as a foam (that was fun), it has lasted me a good four months with twice daily use, and was indeed gentle though a little drying in the winter.

Vanessa actually hasn’t gotten around to trying the toner.  From my use of it I really don’t have much to say.  It was a pleasant toner, and my skin felt fine after using it.  I didn’t notice anything either good or bad after using it.

The soft peeling for me was pleasant, but I am a fan (and my skin needs) of a much stronger exfoliant.  Vanessa, on the other hand, was very happy with this mild exfoliant.  She found it gentle with a good consistency and nice fragrance.  Thumbs up from her on this product.

Both Vanessa and I found the protecting care cream way to thick.  The consistency was almost like an ointment and not a cream.  We both thought it was much too dense and hard to spread on our skin.  This definitely was not the right cream for my oily skin even though my skin is really dehydrated.  Despite my skin dehydration this product was too thick for my skin.  Vanessa did not like the smell of the cream, and she felt it didn’t make her skin soft enough.  If this cream was not as thick I think it would appeal to more people.

The reviving eye care cream was gentle around the eye area and did not cause irritation.  Neither Vanessa or I saw a difference in how our eye area looked after using this cream, but we both found it pleasant and nice.

The last product we both tried was the cooling mineral mask which is really meant more for my skin type than Vanessa’s.  Needless to say we both found the mask strange because after applying the mask it dries and becomes EXTREMELY tight on your face.  So tight it is uncomfortable.  I left it on for the full 15 minutes as instructed, but I did not enjoy those 15 minutes.  My skin did feel soft afterwards but what I had to go through to get to temporarily softer skin wasn’t really worth it.  Vanessa did not like the mask at all.

Bottom Line:  If you have sensitive skin and/or are looking for an organic skincare line with natural ingredients than Dr. Spiller is for you.  I particularly appreciate the fact that these product meet high standards for organic products instead of just slapping a label on the product and that the website shares a plethora of information with the consumer about the products.  Though the products are not cheap they last a long time so you definitely get your money’s worth.

Ingredient Spotlight: Honey January 24, 2013

If you are a fan of DIY facial masks you’ve probably come across more than one recipe for at home facial masks using honey.  Why does this ingredient repeatedly appear in DIY facial treatments?  It turns out for a few very good reasons.   Honey is a humectant, which means it draws moisture to the skin, is antimicrobial, and an antioxidant.

According to Shape magazine honey helps the skin(and your overall health) in a few different ways:

1. Skin ailments: Everything from burns and scrapes to surgical incisions and radiation-associated ulcers have been shown to respond to “honey dressings.” That’s thanks to the hydrogen peroxide that naturally exists in honey, which is produced from an enzyme that bees have.

2. Mosquito bite relief: Honey’s anti-inflammatory properties make it a good option to help reduce the itch and irritation of mosquito bites.

3. It’s an immune booster: Honey is chock full of polyphenols, a type of antioxidant that helps to protect cells from free radical damage. It can also contribute to heart health as well as protect against cancer.

4. Digestive aid: In a 2006 study published in BMC Complementary and Alternative Medicine, researchers found that substituting honey for sugar in processed foods improved the gut microflora of male mice.

5. Acne treatment: According to preliminary research, Manuka, and Kanuka types of honey can effectively treat Acne vulgaris, the skin condition that is caused by inflammation and infection of the pilosebaceous follicle on the face, back, and chest.

(From 5 Health Benefits of Honey)

Future Derm highlights honey’s beauty benefits thusly:

Honey’s combination of vitamins, antioxidants, sugars and amino make it produce hydrogen peroxide and gluconic acid — acidic solutions that are frequently used to clear dirt and bacteria from wounds.  It is due in part to its numerous antioxidants and hydrogen peroxide that honey is often lauded as an anti-bacterial, anti-viral, and anti-fungal agent — good news if you have oiler skin that could collect dirt more easily, have superficial wounds and scarring, or if you just need something to give your skin a little extra cleaning (Indian Journal of Plastic Surgery).

But honey’s effectiveness doesn’t just stop with being a skin cleanser – there is substantial evidence for its role in wound-healing. Coupled with its hydrogen peroxide, honey provides amoist environment for skin to repair itself, encourages epithelialization (skin cell regrowth), granulation tissue formation, (a type of connective tissue), and wound healing.  Plus, honey can reduce swelling and is a strong anti-inflammatory agent, meaning that it very may well reduce pain and irritation from skin lesions (Indian Journal of Plastic Surgery)

Honey is also good for dry skin, especially skin disorders such as Eczema and Psoriasis. These two skin ailments are characterized by their excessive dryness, itchiness, inflammation and irritation. After using the a mixture of honey, olive oil and beeswax three times a day for two weeks, 80 percent of the eczema patients had reduced symptoms of itching, scaling, and oozing from lesions. 63 percent of the psoriasis patients also reported significant improvement in symptoms (Complementary Therapies in Medicine).

Users should know that there are several different strains of honey whose efficacy can vary, such as the medical-quality Manuka and Revamil. If using pure honey, take caution — honey is able to support the bacteria that cause gangrene and botulism, and are typically treated with gamma irridation to eradicate these bacteria (Indian Journal of Plastic Surgery).

(From Lancome Tonique Confort Rehydrating Toner Review)

 

Many sources claim that not all honey is the same and you actually need to use raw honey in order to receive all the benefits described above.  In an article from Beauty at Skin Deep the benefits of raw honey are explained:

It should be noted that not all honey is created equal. Most of the honey found in grocery stores has been processed with heat, which kills off healing enzymes and destroys a lot of the nutrient-rich content. But, raw honey hasn’t been processed and will give your skin the healing benefits that it needs. Also, if you have allergies, try a patch test first and/or ask you physician if raw honey is a right for you.

BENEFITS

Raw honey is an amazing natural beauty solution for all skin types because of its healing skin benefits. It does wonders for a wide variety of skin ailments including:

Acne and enlarged pores
Rosacea
Eczema
Hyperpigmentation
Sensitive, mature, and dull lifeless skin

With its natural pH level of 4.5, raw honey falls within skin’s naturally healthy pH range. Its antiseptic and antimicrobial properties make it great for healing cuts and burns by killing bacteria and fungus. Raw honey also contains gluconic acid, a mild alpha hydroxy acid that brightens the complexion, evens out skin tone, and lightens scars and age spots.

Depending on where the honey is collected from, it contains many nutrients and minerals excellent for skin health such as vitamin B, iron, manganese, copper, potassium and calcium. It also acts as a humectant drawing moisture to the skin and is perfect as a gentle cleansing solution for even very sensitive skin. When mixed with water, honey releases peroxide properties which helps heal acne and impede bacterial growth causing more acne

Chirality and Skincare December 19, 2012

I’ve never pretended that this blog is a skincare blog from a scientific perspective because frankly I’ve never been much of a science student.  When I was studying esthetics and realized that I had to refresh my high school chemistry knowledge (I received Cs in high school chemistry) I nearly had a panic attack.  As I’ve progressed in my work as an esthetician I’ve realized that science knowledge is key to understanding how skincare products work on the skin and key in helping my clients get great results from both treatments and home care products.  But I still need that science to be dumbed down for me or else my mind instantly goes blank.

All of this brings us to the subject of this post – chirality.  I wanted to address this issue since two skincare lines I’ve used make sure to explain that they are both “chirally correct”.  What does that mean exactly and how does that impact skincare products?

The two skincare lines – Glo Therapeutics and Tecniche – each explain why it is important that their products be chirally correct.  (These are just two of many skincare companies that make this claim)

Glo says:

Q: What does “Chirally Correct” mean and why is it important?

A: A molecule is considered chiral if it differs from its mirror image. For example, hold out your hands in front of you. Notice that they are mirror images of each other. If you place your right hand on top of your left hand, you can demonstrate this difference. None of the features of your hands will line up when stacked on top of each other; though they have the same features, they are exact mirors of each other. This means your hands are chiral.

Certain ingredients in glo.therapeutics products are lab produced and will be made of 2 forms: Left (L for left) and Right (D for dextro). These ingredients are mirror images of each other, not exact duplicates. One side of the ingredient is more useful and beneficial to the skin, while the other side is useless. glotherapeutics only uses the purest, highest quality form, making the products superior in the results.

Tecniche has pretty much the same thing to say:

Chirally Correct

Mother Nature creates molecules with two sides or hands, right and left. For reasons unknown to scientists, some right handed molecules work best on skin, where as some left handed molecules are better received by the skin. It may be a more extensive and expensive route, but it has been Tecniche’s™ life work to only use the ‘hand’ of the lab-neutral molecule that best mimics Mother Nature’s perfect plan (aka: Chirally Correct).

Yet is this really necessary in skincare?   Two sources that I’ve read disagree what is stated above.  First to The Beauty Brains and their post Are Cosmedix Products Another Scientific Scam:

Leatha Questions Chirality:

I have started using a skin care line called Cosmedix and they claim that their products are chirally correct. I don`t know what this means and whether it is a marketing gimmick or if there is some truth to it.

The Left Brain Criticizes Cosmedix:

chiral cosmedixThe term chiral is derived from the Greek work for handedness and a molecule is called chiral if it differs from its mirror image. (A simple way to visualize this concept is to think of your right and left hand. You can`t fit your left hand in your right glove, right? That`s because they`re chiral. You can learn more about the idea here.)

Some chemical reactions produce both the left handed and right handed version of the same molecule. These versions are called isomers. This concept is very important in drug manufacture where the Left and Right isomers may have different chemical properties. If the Left isomer is effective against a given disease, you want a chemical reaction that produces pure Left, not a mixture of Right and Left. So for drugs, chiral purity is very important.

But for cosmetic products, chirality isn`t really an issue. That’s because cosmetic ingredients don`t interact with the biological systems of your body the same way drugs do. So your first guess was correct “ this IS a marketing gimmick!

In their book Physiology of the Skin Drs. Draelos and Pugliese agree with The Beauty Brains (page 116):

A term that is being used lately is chirality.  The word chiral is from cheir, the Greek word for “hand”.  A chiral molecule is one that cannot be superimposed on its mirror image, just as you cannot superimpose your two hands in a mirror image.  Any compound that has four different atoms, or groups, attached to a single carbon is chiral.  You need to think about this for a minute or two before you realize that what you are thinking about is an asymmetrical figure, since all chiral compounds lack symmetry by definition.

More and more often, it’s being asked if a product’s chirality is correct.  What should be asked is if the product is biologically active.  Most chemical compounds in nature are chiral compounds that are biologically active, so they are indeed, correct chirally.  Asking if it is “chirally correct” is the same as asking “Is this water in this product really H2O?”  There is no such thing as chirally correct, any more than you can be facially correct.  What should be asked is, “Does this product have the correct optical isomerism?”  By being correct it is biologically active.

So what about some middle ground on this subject.  I found the following post on the blog The Science of Beauty –  What is Chirally Correct Skincare?  I’ll skip quoting the beginning of the post since it contains information I already covered above.  Let’s dive in towards the middle of the post:

Well, whilst some skincare ranges contain only naturally derived ingredients, the majority are comprised of laboratory created ingredients. It is much easier and cheaper to synthesise Vitamin E, for example, in a laboratory than to try and extract it from natural sources. Vitamin E can be found in almonds, sunflower seeds, wheat germ oil, amongst other things but the quantities of these ingredients required to acquire sufficient Vitamin E, and the cost associated with extracting it would make the final skincare product exorbitantly expensive.
When molecules are synthesised by man they always form in pairs that are the mirror image of each other. So, like your left and right hand, these mirror imaged molecules contain all the same parts but are not identical to one and other. Each mirror image of the molecule is given a prefix to its chemical name – either d or l. So, using the Vitamin E example, the chemical name for Vitamin E is alpha-tocopherol so the mirror images of the molecules are called d-alpha-tocopherol and l-alpha-tocopherol. But even though these molecules are nearly identical (the only difference being the mirror image) only one of the molecules can be used by the human body – in this case the molecule with the d-prefix (d-alpha-tocopherol). So chirally correct skincare contains ingredients that have been tested to ensure that they only contain the active molecule, out of the mirror imaged pair, that can be used by the human body. The molecules are sorted so that only the active molecule is added. With Vitamin E it has already been determined that d-alpha-tocopherol the active molecule so any Vitamin E that is added to chirally correct skincare will have been sorted so that only d-alpha-tocopherol is added. If your skincare is not chirally correct, and the vitamin E molecules have not been sorted, it will be listed in the ingredients as dl-alpha-tocopherol, as it contains a 50/50 mixture of the d-alpha-tocopherol and l-alpha-tocopherol molecules.
So what happens if the molecules are not sorted? Generally nothing; however, your skincare will be less potent. When a molecule is made, equal amounts of the l-molecule and d-molecule are created. So, if your skincare range claims to have 10ml of Vitamin E in it, but the Vitamin E has not been sorted to get the chirally correct molecule then your skincare will actually contain 5ml of active Vitamin E and 5ml of a molecule that does absolutely nothing – so your skincare is half as potent as you expect. …
Therefore, there is no reason to be concerned if you are using skincare that is not chirally correct that it could be doing you damage, just be aware that it may not be as potent or effective as you think.

Bottom Line:  Like so many subject that I present in this blog there are truly opposing perspectives here on the same subject.  I think that at the moment I am inclined to agree with those who say that being chirally correct has no place in effective skincare products.  What do you think?  Please share your opinion below.

The Risks of Over Exfoliation December 5, 2012

Usually I can’t say enough good things about exfoliation.  In my eyes regular, at home exfoliation is one of the most essential things you need to do to maintain healthy and beautiful skin.  Depending on your skin type, how your skin is feeling and looking, and what exfoliation product you use you can exfoliate every day or just twice a week.  The thing is – you need to exfoliate.

Why exfoliate?  New Beauty explains why succinctly:

There are many benefits of regular exfoliation. As we get older, skin-cell turnover slows down and exofoliating can help speed up the normal shedding cycle. Exfoliating can rid the skin’s dull, outer layer as well as all of the flaws that reside there, like fine lines, dark spots and blemishes. Plus, your skin-care products can better penetrate your skin. Here are our top four reasons to exfoliate on a regular basis:

1. Even out skin texture. “The granules polish the skin, leaving it with a softer, smoother texture. It’s like using sandpaper on coarse, unevenly textured wood—step-by-step it becomes smooth,” says Los Angeles aesthetician Ole Henriksen.

2. Fight the signs of aging. With age, the skin’s ability to naturally exfoliate slows down. When the skin is laden with dead cells, lines, wrinkles and dryness become more apparent. “Removing dead skin reveals fresher, brighter, younger looking skin,” says Mt. Pleasant, SC, dermatologist Marguerite Germain, MD.

3. Prevent blackheads, whiteheads and breakouts. When the pores get clogged with dead skin and oil gets stuck beneath the surface, pimples can occur.

4. Minimize dark spots. Long after a blemish has healed, a red, brown or purple mark may remain. But each time you exfoliate, you’re removing the top layer of skin to diminish the appearance of discoloration.

(From Four Reasons You Need to Exfoliate)

And what are different ways you can exfoliate?  Once again I’ll turn to New Beauty to explain:

Manual Exfoliation: exfoliates with beads or spheres
This involves physically removing dead skin with scrubbing spheres or beads, which are massaged into the skin by hand. Some ingredients, like ground-up nutshells, can tear the skin and potentially cause infections, so if you choose to use a manual exfoliant, make sure that you use one with beads or spheres, which are less likely to scratch the skin.
The Upside : Quick and easy to use, manual exfoliators are available in a variety of forms and are best for normal skin types.
The Downside: May aggravate acne or sensitive skin.

Enzymatic Exfoliation: exfoliates with fruit enzymes
Ideal for sensitive and mature skin, enzymatic exfoliators contain enzymes that are derived from fruits like pineapple, pumpkin, kiwi and papaya to purge the skin of dead cells.
The Upside: Can be used on extremely sensitive or reactive skin because they tend not to irritate since there is no physical scrubbing. Plus, they’re excellent for really cleaning out clogged pores.
The Downside: “Enzymatic exfoliators take longer to work because you have to let them sit on the skin for awhile,” says Kirkland, WA, dermatologist Julie Voss, MD.

Chemical Exfoliation: exfoliates with acids
Good for acne-prone and sun-damaged skin, chemical exfoliators rely upon ingredients like alphahydroxy (AHAs), betahydroxy, lactic, malic, tartaric, salicylic, retinoic, uric or glycolic acids to break the bond between the dead skin cells, dissolving and removing them.
The Upside: Deep cleans pores, making it a good choice for oily and acne-prone skin types. Exfoliators with AHAs offer anti-aging benefits too.
The Downside: Can cause sun sensitivity and may be too irritating for dry skin. “These exfoliators are usually found in cream or lotion form, rather than being part of a cleanser, so they require an added step,” says Dr. Voss.

But sometimes too much of a good thing well is just too much.  That brings us to the risks of over exfoliation.  Go overboard with exfoliation and risk red, irritated, dry, flaky, and even thin skin.  The New York Times T Magazine article The Peel Sessions explains:

… the search for perfection often leads to just the opposite. Instead of achieving plump, soft skin, some women are winding up with visages that are “thin and kind of stretched, almost like Saran wrap,” according to Dr. Macrene Alexiades-Armenakas, an assistant professor of dermatology at Yale School of Medicine and the director of the Dermatology and Laser Surgery Center in New York. “It puckers like the material would if wrapped tightly on something and looks like if you pricked it with a pin, a clear fluid would come out.”

This is the over-exfoliated face. For the past few decades, the most dominant recipe for radiant skin has called for removing the dead layers of epidermis to reveal newer, brighter, less-wrinkled skin. But not everyone knows just how often to slough, and some women have been misled into thinking that the more often you do it, the better. Or women exfoliate constantly to ensure that anti-aging or anti-acne serums are delivered more effectively. Exfoliate too frequently, though, with chemical peels or Retin A, and you could encounter a multitude of problems: redness, a strange waxy look and, over time, the thin skin Alexiades-Armenakas described. It can look crepelike and translucent, with capillaries showing (if you’re Caucasian), and is far more prone to fine lines, not to mention increasingly vulnerable to cancer-causing UV rays, than untreated skin. For those with darker complexions, overpeeling can also cause hyper-pigmentation, which can be permanent. …

At-home treatments can have their downsides as well. Retinoids like Retin A increase skin turnover and should be used at the correct strength and frequency. “Everyone used to put it on every night — you brush your teeth, you put on your Retin A,” Enterprise recalled. “Cheeks were getting very thin and people had that glossy look. That waxy skin makes you look older and can make you look dated in the same way your hair or makeup can.”

Abuse of drugstore or beauty-emporium products is also a danger. “I’ve done R&D for a large cosmetic company, and unfortunately to launch these over-the-counter peeling agents, the rule of thumb is to recommend twice-weekly use,” Alexiades-Armenakas said. And why is that? “Because if you don’t use it that often, you’re not going to see any results. It’s so weak compared to a dermatologist’s peel, and to compensate for this they have people overuse it.”  …

Of course, disrupting that barrier at just the right rate — either by peels, Retin A, lasers or other means — is how you stimulate the skin into creating collagen. Alexiades-Armenakas is at work on a new method for doing so, testing pixelated radiofrequency technology and ultrasound to push anti-acne or anti-aging drugs into the skin. It’s another form of fractional resurfacing, whose advantage, she said, is that most of the epidermis is left intact. Eventually, according to the dermatologist, this science will make its way into an over-the-counter product, in the form of a hand-held roller.

There remains, however, the conundrum of what to do until those futuristic gadgets arrive. For now, Alexiades-Armenakas recommends relying on a much older technology — that of the body itself. “The skin turns over every 28 days,” she said. “I’m of the firm belief that you’re better off having a strong peel just once a month at most, giving the skin a chance to recover, rebound and rejuvenate itself.”

Furthermore, according to the article Exfoliation: When Is Just Enough … Enough?  by Annet King explains that exfoliation:

… a course of action intended to keep the skin vibrant, supple and youthful, may result in a skin which is more fragilehas less natural ability to protect from UV, is easily sensitized, heals more slowly and lacks in general structural fortitude. Parchment paper comes to mind.

We now know that much of what we call aging is caused by inflammation. And overly aggressive exfoliation, along with other cutaneous assault such as pollution and UV exposure, set off the cascade of dermal interactions known as inflammation.  It is very important to note that skin which is past the age of 25 or so recovers more slowly from inflammation. In fact, inflammation, whether in response to a heavy handed microdermabrasion procedure or some other inflammatory condition such as adult acne, may result in extremely persistent redness—and by persistent, we mean that it may not ever really dissipate.

The good news is, our skin is genetically designed for remarkable resilience. The human skin produces about 1,000,000 skin cells every 40 minutes, which equates to over 36 million skin cells per day. No wonder we think nothing of obliterating them with scrubs, enzymes, acids, sonic brushes and other procedures! …

LESS IS MORE
Gentle exfoliation keeps the debris from accumulating. Today, the market is full of exfoliants which are gentle enough to use daily, such as superfine micropowders and precise dose leave- on serums containing silky microparticles of rice bran, phytic acid or salicylic acid, botanical extract combo’s. These lift dead cell debris, gently resurface using only the mildest bit of mechanical action, and still leave the lipid barrier robust and intact. …

Often, problems arise when clients start to “help the program along” by being over enthusiastic with different products in the confines of their bathroom or while in the gym sauna! Also discuss their comfort-level, perhaps from years in the gym with masochistic fitness trainers, many consumers believe that pain is required part of an effective regimen. This may be true of acquiring a rock-hard six-pack—but it definitely is NOT true of effective skin care.

NIX THE MIX
Combining products and procedures “freestyle”, without the close supervision of a licensed therapist, is where consumers often get themselves into trouble. The trumpeting claims of lunchtime lasers and other medi-office procedures along with powerful products may prove irresistible, especially with the advance of age, and especially with the impending arrival of a pivotal life passage such as a high school reunion or a daughter’s wedding.

Lastly, another reason to stop with over exfoliating – you may be causing breakouts.  According to Allure:

Convincing people that they’re exfoliating too much “is one of my great challenges,” laughs [ Ranella] Hirsch, a clinical assistant professor of dermatology at Boston University School of Medicine. “Over-exfoliating is probably the single most significant cause of breakouts. For some reason, people think exfoliating means ‘torture my skin like it has secret government information.’” In particular, Hirsch shakes her finger at skin-care overachievers: “The person who is exfoliating too much is also putting on actives [such as Retin-A and salicylic and glycolic acid], is doing facials, is doing microdermabrasion. Each of those things on their own is good, but when you add every form of treatment together it leads to injury.”

So how can you exfoliate effectively?  Once again according to Allure:

Hirsch insists that for the most part skin knows how to exfoliate itself and says using just one exfoliator should be enough. And instead of having a set routine for how often you use your product, leave it up to your face. In other words, don’t exfoliate because it’s 7AM—exfoliate because you feel like you need to. “You have to listen to your skin,” says Hirsch. “Something that’s right at one moment can shift in real time. Just listen and adapt.”

Bottom Line:  Everyone needs to exfoliate just don’t overdo it.  Check in with your skin regularly to see if you need to adjust your exfoliation routine.  Strive for balance (I know – much easier said than done)  Experiencing breakouts and clogged pores turn to a salicylic acid product for exfoliation.  Flaky yet normal skin?  You could use a gentle scrub.  Want an effective anti-aging product?  Find the right retinol or Retin-A product for you.  Just remember – when your skin starts to feel irritated and sensitive or is constantly red you could be overdoing it.  Then it is time to reevaluate your exfoliation routine.  Keep in mind that correct exfoliation will make your skin soft, smooth, and bright.  Since everyone is different don’t look to others – figure out what your skin needs.  Check in regularly with your skin to make sure you are doing what is best for your skin.

Baking Soda – A Great Natural Exfoliant? November 26, 2012

I’m not someone who usually makes her own skincare products except for the occasional body scrub from sugar and oil (you can read about my misadventures in trying to make my own beauty products here).  I am very diligent about facial exfoliation though it has never occurred to me make my own facial exfoliant.  Yet again and again I’ve seen baking soda recommended as a DIY exfoliant (even Arm & Hammer recommends you do this).  So is it really ok to put baking soda on your face and scrub away?

I’ll turn to The Beauty Brains for some explanations from their post Is Baking Soda an Effective Natural Exfoliant?:

Baking soda (aka sodium bicarbonate) falls under the category of physical exfoliants, and what makes it especially effective is that it is a fine, yet hard powder, making it highly effective at removing the dead skin cells without causing excessive irritation. Chemically speaking, baking soda is acid neutral, and acts a mild buffer which means that it has the ability to neutralize other substances it comes in contact with that are acidic (like vinegar) or basic (like soap). Many people also believe that baking soda has cleaning properties; however, scientific evidence has shown that this is due to baking soda’s physically abrasive nature, and it is not an effective anti-microbial agent.

Exfoliating with baking soda

To reap the benefits of exfoliating with baking soda, add a teaspoon of the powder to your facial cleanser, mix well, and massage into skin like you would with a commercial exfoliant. Do this 2-3 times a week or as per your regular exfoliation routine. If you notice that your skin is red or irritated afterwards, try putting in less baking soda and use the treatment at night so that your skin has a chance to get back to normal while you sleep. Remember to always moisturize afterwards!

Baking soda as an acne treatment

While there are numerous testimonials in which people claim that baking soda cleared up their acne when nothing else helped, please remember to take these statements with a grain of salt. We don’t know what else that person had changed in their skin regimen; it’s possible that besides using baking soda they also started drinking more water, switched their cleanser or moisturizer, or maybe even changed the number of times they cleanse their skin per day. Seasonal changes and stress levels also have a very strong impact on how much and how noticeable your acne may be. However, there is some evidence that baking soda may be beneficial in treating acne since just the exfoliating properties of baking soda alone lead to an increased skin cell turnover rate making your acne look less noticeable. Plus, baking soda’s neutralizing properties maybe reduce redness of the skin also reducing the appearance of acne. If you want to try using baking soda as an acne treatment, my recommendation is to use one teaspoon of it in your cleanser at night to exfoliate your skin, as well as make a thicker paste of just baking soda and water and apply it to the acne as a mask for 5-10 minutes or overnight (beware, when it dries the mixture will crumble so you might up wake up to a messy pillow).

The Beauty Brains bottom line

In summary, all signs point to baking soda being an excellent and cheap physical exfoliant. It is ph neutral and a fine powder, which means that it will be gentle on your skin. Baking soda may also be useful in treating acne when made into a paste and applied to the affected areas although there is not as much scientific evidence to back that up.

(As an aside I want to mention that I was actually taught, though I never tried it, while in esthetics school that if we didn’t have another way to exfoliate skin we could use a mixture of baking soda and water.)

I thought for the purposes of this post I should try exfoliating with baking soda.  I added about a half a tablespoon of baking soda to my gentle cleanser one night and gently scrubbed away.  I found the baking soda felt very harsh on my skin, too harsh almost, but my skin did feel very soft afterwards – if only for that night.  Because I found the baking soda too  harsh I would think twice before using it again.  (I should mention that I use prescription Retin-A on a regular basis so my skin tends to be more sensitive to exfoliating products)

Bottom Line:  As long as you aren’t using a lot of other exfoliating products you can try baking soda a few times a week as a mild scrub to exfoliate.  Just keep in mind that a scrub will remove surface dead skin cells and will not penetrate into your pores in order to unclog pores or dissolve excess oil.  I would definitely not believe the internet hype that using baking soda cures acne.  Keep in mind what The Beauty Brains had to say above about that phenomena.

Why Does Mineral Oil Have Such A Bad Reputation? November 5, 2012

A very long time ago a reader asked me to address the issue of mineral oil in my blog.  I am just now getting around to writing this post.  My apologizes to that reader.

Let me start off with information about mineral oil that I found on the holistic lifestyle website The Chalk Board:

Toxic Tuesday Ingredient Focus: Mineral Oil (aka Paraffinum Liquidum)

WHAT IS IT? An extremely cheap & common petroleum derivative (refined crude oil petrochemical) which is found in 98% of skincare products sold in the US.

HEALTH RISK: Petrochemicals contain neurotoxins which damage the nervous system. Mineral oil forms a film on the surface of your skin that can not be absorbed, thereby blocking the pores and the skin’s natural respiration. It traps dirt and bacteria and blocks the absorption of vitamins/minerals/botanicals that may be in a product. John Hopkins University named mineral oil in cosmetics and moisturizers as the number two cause of aging (first being direct exposure to sun). It may also cause allergic reactions and dryness, as well as promote acne and other skin disorders.

Oy!  If I took everything I read at face value I would be throwing out my beauty products right now instead of writing this post.  Scary information, right?  Extreme information, right?  (I recently did a training with a very well known international skincare company during which the trainer repeated the same information about mineral oil that you see above)  So what’s the truth about mineral oil?  What was written above or is it something else?

In his book The New Ideal in Skin Health Dr. Carl Thornfeldt devotes three pages just to the topic of mineral oil.  He debunks the information above (pages 377-380):

One of the most widely used ingredients for moisturizers is the first controversial ingredient we will cover.  Petrolatum (also known as petroleum jelly and white petroleum) and mineral oil have been much maligned from “natural” based cosmetics companies, internet consumer sites and other environmental groups.  These sources erroneously claim that petrolatum and mineral oil are terrible ingredients because they come from crude oil (petroleum) which causes harm to the skin by forming an occlusive oil film, thereby “suffocating” it.  Unfortunately for these sources, this claim defies known human biology. In the body oxygen is transported to the skin by the blood supply, and then diffuses into the epidermal cells – oxygen is not absorbed directly from the air.  Herbal mucilages have been used for wound healing to soothe, protect and heal damaged or abnormal skin for centuries.  These mucilages naturally mimic the occlusive activity of petrolatum and mineral oil.  However, the “suffocating” claim is never used to dissuade use of those types of products.

Mineral oil, also known as soft paraffin, is the liquid form of petrolatum.  All of these ingredients consist of mixtures of hydrocarbons that are byproducts of crude petroleum distillation; thus they are all actually organic, natural ingredients. …

Mineral oil reduces TEWL (transepidermal water loss) by 40%, is equally as occlusive as coconut oil and more occlusive than linoleic acid, yet it does not induce acne.  Mineral oil and petrolatum provide inhibition of excessive inflammatory activity superior to 1% hydrocortisone is treating soap induced contact irritant dermatitis conducted by this author.  It has also been documented these ingredients have anticarcinogenic and mild antibacterial effects.

Many of these misconceptions regarding safety and efficacy of these ingredients are directly related to the quality of the grade.  Technical grade is the least unpurified form of the oil, and is commonly used by machinists to lubricate engines and equipment.  It is known to induce contact reactions in 10-50% of the machinists.  Cosmetic grade is a more purified option.  The highest standard is United States Pharmacopeia (USP) pharmaceutical grade, which indicates that it is essentially free of impurities.  …

Prescription pharmaceuticals and some cosmetic companies do use the highest quality USP grade in their marketed formulations.  Cosmetic companies are not required to use USP grade, even though USP grade mineral oil and petrolatum are considered the safest, least irritating moistutrizing ingredients ever found in the skin care industry.  In addition, they are commonly used as a “vehicle” for most substances used in patch testing by dermatologists due to their nonirritating and nonsensitizing properties.  This is a medical diagnostic process used to determine if one is allergic to ingredients in products applied to the skin.

Neither pharmaceutical nor cosmetic grades of petrolatum or mineral oil are considered comedogenic when using the standardized comedogenicity testing.  With the highest comedogenicity rating at 5, these ingredients have tested at a 0-1 rating.  This rating indicates the increased impurities in lower grades appear to be the major cause of adverse reactions including comedogenicity, contact irritant and allergic dermatitis. …

As to claims that people react negatively even to USP grade petrolatum or mineral oil, to date all compounds used in skin care have at least one documented positive patch test response.  Even purified water applied to the skin may activate hives in people afflicted with a disease called aquagenic pruritus.  Thus, while safety testing is imperative, there can always be the exceptional patient that may react negatively to even the safest known ingredient.

If that information isn’t enough to persuade you that mineral oil in skincare products is ok let me present some more evidence.  The Beauty Brains debunked five long-held myths about mineral oil in their post The Top 5 Myths About Mineral Oil – Part 1:

We often see the advice that people should avoid mineral oil at all costs.

This idea is propagated by numerous “natural” companies. Well, this advice is just bogus. It’s not based on any scientific studies. Mineral oil is a perfectly fine ingredient and has been used in cosmetics for over 100 years.

Here are the top 5 Myths that companies tell people to make them afraid of mineral oil.

Mineral Oil Myths

1. Mineral oil is contaminated with carcinogens. While it’s true that some petroleum derivatives contain carcinogenic materials (like some polycyclic aromatic compounds) the mineral oil that is used in the cosmetic and pharmaceutical industry is highly refined and purified. It’s purity is even regulated by the US FDA and other international regulatory agencies. There is absolutely no evidence that cosmetic grade mineral oil causes cancer. And there has been plenty of testing done to ensure that fact. We could find no published reports in any of the dermatological or medical journals indicating a link between mineral oil and any forms of cancer.

2. Mineral oil dries the skin and causes premature aging. Mineral oil works as a barrier between the skin and the air. It acts as an occlusive agent which prevents water from naturally leaving your body through your skin. It will not dry out your skin or cause premature aging. Quite the contrary. It will provide moisturization.

3. Mineral oil robs the skin of vitamins. Since many vitamins are oil based, people assume that mineral oil will pull them out of your skin. There is no legitimate scientific evidence that this is true. Mineral oil has no effect on the vitamin levels in your skin.

4. Mineral oil prevents absorption of collagen from collagen moisturizers. Collagen in your skin lotions and moisturizers is too big to actually penetrate your skin. Therefore, mineral oil will have no effect on whether the collagen gets absorbed or not.

5. Mineral oil causes acne. In some people, mineral oil can exacerbate acne problems. However, most people will not experience any problems.

So, if it is not for safety concerns, why would companies be telling you to avoid mineral oil? We’ll look at that in part 2 of our series.

The Beauty Brains Bottom line. Mineral oil is NOT bad for you or your skin. It is one of the best ingredients available in skin lotions and moisturizers. It is also 100% natural taken directly out of our dear Mother Earth.

Next I’ll turn to the blog Lab Muffin to further debunk a few mineral oil myths (From the posts – Is Mineral Oil Dangerous? Part 1 and Is Mineral Oil Dangerous? Part 2):

Mineral oil comes from crude oil… I’m not putting gasoline on my face! - FALSE

While it’s true that mineral oil comes from crude oil, it doesn’t mean that its properties are the same, or even similar to gasoline!

Crude oil is formed when biological material (from algae and plankton) gets buried under the sea. Over millions of years, the pressure transforms the carbon-containing compounds in the once-living tissue into the carbon-containing compounds which make up crude oil.

Crude oil contains lots of different things, mainly made up of carbon and hydrogen only. After it’s been pumped out of the ground, it has to be refined to separate out the different bits.

Apart from mineral oil and gasoline, things that come from crude oil include paraffin wax (found in most candles, and in cheese wax) and asphalt/bitumen. And as you know, candles and gasoline and asphalt are completely different! So just because it comes from the same stuff at the beginning doesn’t mean it’ll look, act or be the same.

Mineral oil is comedogenic and will make you break out - FALSE

Mineral oil appears on a large range of “comedogenic ingredients” lists. Once upon a time (well, in the 1970s), cosmetic companies noticed that a lot of women started getting acne from their makeup products. One scientific study on comedogenicity used the inside of a rabbit’s ear to test whether products caused pimples, and this quickly became the test of choice. However, later on, they found that sometimes the results on a rabbit and the results on a human were different. (Lab Muffin loves rabbits, and this made her sad, because an awful lot of rabbits got ear pimples for no good reason!)

A later study tested products containing between 0 and 30% mineral oil, and found that it wasn’t comedogenic on human skin. The best thing about mineral oil is that (unlike a lot of plant oils) it’s incredibly stable – it doesn’t oxidise, and stays liquid. In other words, it’s not likely to clump up later on, after reacting with oxygen and light, and clog your pores! However, this doesn’t mean that it won’t cause you to break out, since different people respond differently to certain ingredients.

It just sits on top of skin – it doesn’t moisturise! It suffocates your skin - PARTLY FALSE

There are three ways in which moisturisers moisturise – occlusive (covering your skin up so water can’t evaporate), humectant (grabbing water and keeping it next to your skin) and emollient (makes your skin feel soft) actions. Mineral oil is an excellent occlusive, so yes, it does just sit on top of your skin – but it definitely moisturises! In fact, scientists often use it as a standard for comparing other moisturisers. Of course, if you have dry skin to begin with, just putting mineral oil isn’t going to work so well (if there’s not enough water to begin with, there’s not much water to keep in!).

As to whether skin can be suffocated – skin is porous, but it doesn’t really need to “breathe”. What people usually mean by “letting your skin breathe” means washing off the dirty gunk from your pores… dirt can stick to mineral oil, just like it can stick to anything else on your face.

Because mineral oil is really good at being an occlusive, it’s possible that it can block certain nutrients in your cream from reaching your skin – the solution is to put on the active ingredient first, then cover it up with the mineral oil, and the mineral oil will keep that stuff on your skin.

Lastly, now that my sources have debunked the different myths about mineral oil perhaps you are asking yourself – if mineral oil is good for our skin why do I need another moisturizer?  Once again I’ll turn to The Beauty Brains to explain (from Why Can’t I Just Use Mineral Oil?):

Yashendwirh says…I’ve read here and several other blogs that mineral oil, vitamin-E and a few other very inexpensive products are both hydrating and non-comedogenic. Would that make them effective every day go-to moisturizers? That said, what is the benefit of spending anything more than the couple bucks it costs for these products on expensive moisturizer formulas?  Even inexpensive ones that are $10-$20 seem expensive compared to the $3 it costs for an absolutely enormous bottle of mineral oil? We know it works, why would we throw our money at anything else? Would I be doing my skin a massive disservice by forgoing my current moisturizer (clinique gel) in favor of using mineral oil long term?

The Right Brain replies

You certainly won’t be hurting your skin by using mineral oil but you may be missing out on some of the benefits of a fully formulated product. Here are three examples:

1. Balanced moisture
Fully formulated lotions contain water and ingredients that can attract water to your skin like glycerin. You won’t get that with just mineral oil.

2. Non-greasy feel
Compared to modern lotion formulas which feel nice and soft on the skin mineral oil can leave you feeling a bit, well, oily.

3. Special function ingredients
Creams and lotions can deliver sunscreens and retin-A which are both important anti-aging ingredients that you won’t get from just mineral oil.

Bottom Line:  Don’t let mineral oil scare you.  It’s an effective and worthwhile skincare ingredient.

Ingredient Spotlight: Witch Hazel October 28, 2012

Filed under: Ingredients — askanesthetician @ 7:00 am
Tags: , , , , ,

Allure places it in its ingredient hall of fame, Paula Begoun says to avoid using products that contain it.  So what who should you believe?  What does witch hazel do for your skin?

Let’s begin with some facts about witch hazel:  it’s a very commonly used cosmetic ingredient that comes from the bark and leaves of the hamamelis virginiana plant.  I learned the following from the book The New Ideal in Skin Health (pages 318-319):

Topically used to treat cutaneous inflammation, swelling, itching, injury, hemorrhoids, insect bites and stings, minor burns and irritations.  Active elements include bitters, essential oils, gallic acid, and tannins.

Types of Products:  Skin fresheners, astringents, local anesthetic, vein cosmeceuticals

Functions:  Anti-inflammatory, antimicrobial, antioxidant, astringent, elastin synthesis stimulant

Adverse Effects:  The alcohol content contained in witch hazel can be a skin irritant

Clinical Studies:

a.  One clinical study shows Witch Hazel to be less effective in reducing UV-induced erythema than 1% hydrocortisone.

b.  It was shown to reduce inflammation and pruritis in 36 atopic dermatitis patients.

Why does Allure love witch hazel so much?  In the Daily Beauty blog post entitled Ingredient Hall of Fame: Witch Hazel they explain

For centuries, witch hazel has been known for its soothing and cleansing properties, but right now, one of our Web editors is going completely nuts over the stuff. While searching for an alternative to her over-drying cleanser, she tried a witch hazel-infused one, and it did the trick, degreasing her skin, without drying or stripping it.

“Witch hazel is a natural astringent,” says Kenneth Beer, a cosmetic dermatologist in West Palm Beach. “It removes surface debris and oil, and has a long history of safety and efficacy.” Hmm. No wonder why it’s in tons of popular face cleansers, treatments, and atomizers.  …

Bottom line: Witch hazel is the Madonna of skincare ingredients—it takes many forms and has been around forever.

But before you rush out to buy some witch hazel keep a few things in mind.  My Consumer’s Dictionary of Cosmetic Ingredients has the following to say about witch hazel (I have the 6th edition of the book, page 546):

One of the most widely used cosmetic ingredients, it is a skin freshener, local anesthetic, and astringent made from the leaves and/or twigs of Hammamelis virginiana.  Collected in the autumn.  Witch hazel has an ethanol content of 70 to 80 percent and a tannin content of 2 to 9 percent.  Witch hazel water, which is what you buy at the store, contains 15 percent ethanol.

[So then the question really becomes - what does ethanol do to your skin?  Well that readers is a whole other debate that I really can't get into here in this post (or would want to).  Cutting to the chase - ethanol is an alcohol and there are varying opinions about how alcohols (we aren't talking about alcohol that you drink, by the way) impact the skin.  I would suggest reading the following blog posts from Future Derm for more information about ethanol and about alcohol in skincare products:  Why Alcohol in Skin Care is Safe, Despite What Paula Begoun Says and Is Ethanol in Skin Care Products Safe?)]

Just how is witch hazel transformed into an ingredient that can be used in cosmetic products.  The Beauty Brains explain in their post How Does Witch Hazel Work?:

In its natural form witch hazel is a shrub that can grow to be 10 feet tall, or more. It has oval leaves and slender petals. In autumn,  the plant is harvested by cutting the branches to the ground and chipping the wood and leaves into little bite size pieces. This mulch is then transferred to large stainless-steel vats where it is steam distilled for thirty-six hours. After “stewing” the extracted mixture is condensed and filtered and ethanol is added as a preservative. (Depending on the exact processing, the witch hazel may contain more or less tannins. The mixture of plant parts also controls the tannin content – bark contains 31 times more tannin than the leaves.) The resulting liquid is bottled and sold to drug stores as “witch hazel.”

Paula Begoun’s objections to products containing witch hazel rests on the fact that you don’t know what you are getting in your product and because of possible skin irritation.  She explains:

Commonly used plant extract that can have potent antioxidant properties (Sources: Phytotherapy Research, June 2002, pages 364–367; and Journal of Dermatological Science, July 1995, pages 25–34) and some anti-irritant properties (Source: Skin Pharmacology and Applied Skin Physiology, March-April 2002, pages 125–132). However, witch hazel’s high tannin content (and tannin is a potent antioxidant), can also be irritating when used repeatedly on skin because it constricts blood flow. The bark of the witch hazel plant has higher tannin content than the leaves. Steam distillation for producing witch hazel water removes the tannins, but the plant’s astringent qualities are what most believe give it benefit. Alcohol is added during the distillation process, the amount typically being 14–15%. Witch hazel water is distilled from all parts of the plant, so in that sense you never know what you’re getting, though the alcohol content remains (Source: http://www.naturaldatabase.com; http://www.drugs.com). Depending on the form of witch hazel, you’re either exposing skin to an irritating amount of alcohol (which causes free radical damage and collagen breakdown), tannins, or both. Moreover, witch hazel contains the fragrance chemical eugenol, which is another source of irritation.

Personally I remember drying my face out with the use of a witch hazel astringent when I was a teenager with acne.  Now I know that the added ingredients in the product caused my skin to feel dry and tight not the witch hazel itself.  As a stand alone ingredient witch hazel has many skincare benefits.  When buying a product containing witch hazel look to see what the witch hazel is mixed with to make sure that you are getting the real benefits of this ingredient and not suffering side effects from the other ingredients in the product.

Can Anyone Use Retin-A? October 11, 2012

Recently a long-time reader of this blog (thank you Louise for all your support!) asked me to address the issue of Retin-A use in my blog from a different angle than I have before.  So far the posts I’ve written about Retin-A have been an overview post on the subject (All About Retinol) and another post explaining why Retin-A remains the anti-aging superstar ingredient that it is (Back in Vogue: Retin-A).  Though this post will have some overlap with my past posts about Retin-A and retinol I do hope that this latest post will help explain how anyone can use Retin-A or retinol effectively and just how to do that.

I think it is best to start this post with a summary – what does Retin-A do and what is the difference between the different Vitamin A derived ingredients we see in skincare products?  Dr. Leslie Baumann does a good job of breaking things down:

First and foremost, retinoids speed the rate at which skin cells turn over, which means they thin the layer of dead skin cells and help keep healthy, younger-looking cells on the surface. Retinoids also promote the skin to produce more collagen while preventing the breakdown of existing collagen.This thickens the dermal layer of skin and helps minimize the appearance of lines and wrinkles. Here’s the lowdown on the different members of the retinoid family, which are all derivatives of vitamin A.

Beta carotene: If you eat too many carrots and your skin turns orangey yellow, it’s because you’ve ODed on beta carotene. (Don’t worry, it’s actually good for you.) This is a great antioxidant, so it’s important to get beta carotene from food. Don’t waste your money on topical creams with carrots or beta carotene because it does not absorb when applied to the skin.

2.Tretinoin (Retin-A): Perhaps the best known retinoid (and the gold standard for skin improvement), tretinoin got its start as an acne treatment before its inventor, Albert Kligman, MD, realized that patients on the medication had less wrinkles than those who were not. Dr. Kligman then developed Renova, a tretinoin cream that got FDA approval for the treatment of wrinkles. A little fact: Tretinoin does not cause sun sensitivity, however it is less effective when exposed to UV light, and this is why it’s best used at night. Other brand names of tretinoin now include Atralin (formulated with hydrating glycerin), Refissa, and Retin-A Micro.

3.Adapalene: This is considered a second-generation retinoid because its chemical structure is different than naturally occurring retinoids. The brand name is Differin, and it is more stable when exposed to the sun and less irritating. The prescription EpiDuo contains adapalene and benzoyl peroxide to help fight acne. In recent news, adapalene is now available as a generic.

4.Tazarotene: A third-generation retinoid, this is stronger than adapalene, less irritating and more sun-stable. I like it for patients who have been able to tolerate tretinoin and/or adapalene without any problems.

5.Retinol: This is the over-the-counter version of tretinoin, but the big drawback is that it’s very unstable, and the product packaging is crucial for its effectiveness. Johnson & Johnson has had the patent on retinol packaging, which is why my favorite OTC retinols are from RoC and Neutrogena. It’s much weaker than tretinoin, but studies do show it works to improve wrinkles. I like to start my patients on retinol and then work them up to tretinoin, and then tazarotene.

6.Retinyl esters (retinyl palmitate and retinyl linoleate): These ingredients are broken down into retinol once they’re applied to the skin. However, it takes time for them to absorb which is why there’s some controversy surrounding retinyl palmitate—based on a report by the Environmental Working Group. They aren’t irritating (because they don’t really absorb), but they don’t really work, so I say skip them.

7.Retinaldehyde: This penetrates better than retinyl esters, but not as well as retinol (which is why it’s less irritating). If you’re looking for results and bang for your buck, stick with retinol or a prescription.

(From Retinoids: An Essential Ingredient for “Wrinkled” SkinSkin Type Solutions LibraryTips)

As great as Retin-A is for the skin many people cannot use it because it causes them too much irritation.  The Vogue article The Return to Retinol explains:

The thing is, Retin-A and its various prescription descendants (Renova, Tazorac, Differin)—may have launched a thousand lineless faces, but they also launched as many irritated ones: scaly, red, angry. In those early days (fifteen years ago), retinoids could be used only at night because of their sensitivity to light; they could make skin extra-sensitive and made time in the sun, even incidental exposure, a cardinal sin. “Everyone was really excited from the beginning, but the big issues were dryness and irritation—mostly because people would apply too much,” says dermatologist Fredric Brandt, M.D., the New York– and Miami-based skin-care Svengali who has thousands of seemingly ageless women in his thrall (retinoid enthusiasts Madonna and Gwyneth Paltrow included). But even when skin wasn’t in outright crisis mode, a telltale sort of “retinoid face” could develop: spookily taut and shiny, like Barbie plastic. This is because the retinoic-acid molecule works a little too well: It’s so tiny it can penetrate all the layers of the skin, prompting extra-speedy cell turnover and exfoliation in the process. “You’re helping fix photo-aging, brown spots, acne, roughness, and collagen breakdown,” says Brandt. Miraculous, yes; gentle, no.

So what can you do in order to prevent irritation if you want to use Retin-A (and I personally strongly recommend Retin-A for those people who want to combat the signs of aging or who have acne and have tried numerous other anti-acne treatments to no avail), but cannot live with flaky, irritated, and red skin?  Start off slowly – use a retinol, an OTC product, before using a prescription product. You can try a product that is meant for sensitive skin like ROC Retinol Correction Sensitive Night Cream  (truthfully I don’t know how well this product works, but it worth a try if you have sensitive skin or are wary of trying a stronger product)  first before working your way up to a stronger product.  In a sense you will prepare your skin to tolerate stronger prescription products in the future.  According to Dr. Ellen Marmur in her book Simple Skin Beauty there are a few other ways to prevent skin irritation associated with using Retin-A (pages 278-279):

Prescription retinoids are the strongest and most effective form of retinoic acid.  Over-the-counter products contain milder vitamin A analogs; either retinol or retinyl palmitate (retinyl palmitate beign the weakest).  In order to have an effect on retinoid receptors, these must be converted to retinoic acid inside the body, and that conversion may not happen with the trace amount of low-strength vitamin A contained in a beauty product.  Although the results are therefore inconsistent, an OTC retinol might be worth at try if you’re skittish about using a prescription medication or if you have especially sensitive skin.  Stabilized, high-strength retinol may be somewhat effective, but look for one that states the percentage of retinol on the label.  Otherwise there’s probably just a tiny, ineffectual amount in the product.  (Personally, I would rather use a prescription retinoid with a percentage of medication that I know works.)

Side Effects:  Retinoic acid is a drug and there are risks associated with its use.  Since it decreases sebum (remember, this is still an acne medication), it makes the skin extremely dry.  (If that’s the case for you, applying moisturizer on top of retinoic acid is the answer, and it won’t dilute its potency.)  It makes the skin photosensitive, so daily sunscreen is a must – which is also why retinoic acid should be used at night.  It tends to irritate even moderately sensitive skin, so be careful not to overdo exfoliants such as glycolic acids (one a week is plenty).  For the same reason, be sure to stop using retinoids three to five days before having any skin procedures done, from simple waxing and facials to medical peels or lasers.  For those who have a hard time tolerating even a low-dose prescription retinoid, I recommend trying short-term applications: apply a pea-size amount over the whole face and neck, leave it on for fifteen minutes, then rinse it off.  You may get the same benefits as wearing it overnight.

Another thing to keep in mind is that even though having flaky and red skin is a side effect from using Retin-A it is a temporary one.  Your skin will get used to the product and those skin irritations will gradually disappear.  But if you live in a cold or dry climate your skin might constantly feel dry with Retin-A use.  Simply use a moisturizer twice daily at least or more if necessary to combat this dryness.  Be sure to wait about 10 or 15 minutes after applying your Retin-A before applying your moisturizer on top so that you allow the Retin-A to absorb properly into your skin.  Lastly, keep in mind that Retin-A comes in a wide variety of formulations.  Refissa, for instance, is a 0.05% tretinoin cream that is buffered so that it causes much less irritation for the user.  Many people do not peel at all when they use this product.

Summary of Different Ways to Prevent Irritation When Using Retin-A:

  • Only use a pea size amount for your entire face.  There is no need to use more.
  • Start off slow – use your Retin-A only twice a week or every other night for at least two weeks before determining if you want to use it more often.  For some people using Retin-A twice a week is enough.
  • If you are wary of using a prescription product start off with an OTC product.  Be sure to follow the manufacturer’s instructions for use.  After using a product like this for a few months you can move on to prescription one.
  • Ask for a prescription buffered product like Refissa if you know your skin is reactive and/or dry.
  • Work through the initial phase of irritation. That means be patient – you’ll see results in about three months.  Don’t give up on the product before then.  If you start and then stop and then start again using Retin-A your skin will get stuck in phase one of use.  Simply put your skin will constantly be irritated and red.
  • Use a moisturizer on top of your Retin-A.  Some of my favorite moisturizers to combine with Retin-A use are the renewal products from Epionce.  Be sure to wait at least 10 minutes after applying your Retin-A before applying a moisturizer on top.
  • Avoid irritating your skin further by overusing other facial exfoliating products like glycolic acid.  Products with Vitamin C can even be too irritating for some people if they are using Retin-A.
  • Use sun protection daily.
