Buyer Beware: Skincare Claims to Look out For January 20, 2011

I’ve written a post in the past about how to be savvy skincare product consumer, but once I wrote my post explaining what cosmeceuticals are I decided that it would be a good idea to write yet another post which goes into greater detail on the subject of skincare product claims versus reality.

One of the best explanations that I have ever come across that explains how to cut through the hype surrounding skincare products is from Daniel Yarosh’s book The New Science of Perfect Skin.  Overall I wasn’t a great fan of this book overall (see my review of the book), I did really like chapter 2 of the book: Cutting Through the Hype.  This chapter does a fabulous job at explaining how cosmetic companies market their products to consumers and how you can protect yourself from being had by false claims.

For example Yarosh points out (page 41):

Realize that large-scale manufacturers may (or may not) spend a lot of money on research, but they also have to satisfy a broad range of customers, and that means they avoid many specialty ingredients that might work for a few but that might prove irritating to some consumers.  So they sacrifice effectiveness for ingredients that have broad appeal.  …  Many dermatologists have entered the skin-care market in the last few years, and some have terrific products.  Others are good but not worth the markup.  Bear in mind, too, that dermatologists selling their own lines may or may not have had a hand in the lines’ development.  Some buy off-the-shelf products from popular suppliers and simply place a label with their name on it and pass it off as their own.

One of the more interesting things I learned from reading Yarosh’s book was how the cost of a product is determined (pages 46-48).  We all know that high price doesn’t equal a better quality product so where do these high prices for products come from?  According to Yarosh, the price of a product is determined by the cost of its raw ingredients and the production overhead. Regardless of that determination the high price of a skincare product might just be part of a marketing strategy in order to convince the consumer that they are worth investing this type of money in themselves and the care of their skin.  Some companies are simply trying to see how much they can charge for a product and get away with it.

For a breakdown of how the money you pay for a product is actually used by a manufacturer I’ll turn to Yarosh again for an explanation (page 48):

Let’s say the [high-end anti-aging] product [you might buy at a chain drugstore] costs thirty dollars.  The first fifteen dollars goes to the store, of which three dollars is kicked back up to the chain headquarters to support the national television advertising and circulars that stuff your mailbox.

That leaves fifteen dollars for the manufacturer.  He uses about seven of those dollars for his own advertising campaign in the glossy women’s magazines and sexy billboards along the highway.  So a total of at least ten dollars (three from the chain and seven from the manufacturer) of the original thirty-dollar price tag goes into trying to convince you to buy the item.

That leaves eight dollars of the original thirty for the product itself.  The manufacturer will use four dollars or more of that to buy a nice bottle and put it in a package with perhaps a false bottom, great graphics, and an enchanting name.  And for going to all that trouble he needs at least two dollars in profit per jar.

That leaves just about two dollars of the original thirty for all the ingredients, including the cream base, the pH adjuster, the emulsifier, the fragrance, and the preservative.  If there is anything left over, it just might go into the latest high-technology botanical extract that is greatest discovery of the century and will completely revitalize your aging looks!

Bottom line: High price and rare ingredients don’t prove anything, but low price means a product probably hasn’t incorporated new technology.

How to Protect Yourself For Falling for False Claims and Bogus Promises

In order not to succumb to advertising hype when you go shopping for skincare products keep a few other things in mind –

  • The photos in skincare and cosmetic ads are photoshopped to an inch of their lives!  The models do not really look that way in real life!  Putting on the cream in the ad will not make you look like the model or the celebrity in the ad because even they don’t look that way.  Remember that a lot of skincare products ads, no matter who they are targeted at, use very young models to promote them.  If you are 45 you will not look like the 25-year-old model in the ad.
  • Don’t believe before and after photos.  I have to admit that I love before and after photos and I love make-overs.  But if you look closely at before photos you’ll probably notice that the lighting and the make-up (or lack of make-up) is different from the after photos.  There is a reason for that.  The manufacturer wants you to see a difference between the photos so they will do whatever it takes – new haircut, better make-up application, flattering lighting – to distract you from noticing on little has actually changed with the person’s skin.  Don’t fall for it.
  • Read the words of ads carefully; they are vague for a reason.  You’ll see the words “helps”, “fights”, “may improve”, “may enhance” for a reason – the FDA requires that manufacturer use words like that because otherwise they would be making a false claim on how their product works.  This intentionally vague language this leads to lots of confusion on the part of the consumer which only helps the manufacturer in the end.  Look at the ingredients in a product, don’t read the ad copy or the blurb on the side of the package.


What About Scientific Studies and Other Endorsements?

Once again according to Yarosh (page 52):

A typical pseudoscientific study [in a skincare product ad] will say something like “76 percent improvement in wrinkles,” implying that one can expect three-quarters of facial wrinkles to disappear.  But upon inspection, the study asked participants whether they noticed any difference, and 76 percent said yes.  You don’t have to be good at math to realize that the fact that 76 percent of a group liked a product is not the same as a 76 percent improvement.  It could have simply been a 1 percent improvement noticed by 76 percent of the panelists.

The best type of doctor administered patient studies of a product are double-blind, placebo-controlled studies.  This means that the doctor administering the study doesn’t know whether the medication or product he is giving the study participants is an active drug or a placebo.  The patient also doesn’t know hence the double-blind part of the study.  All of this ensures that the results of the study are not biased by either side.  These studies are rarely if ever done with cosmetic and skincare products because they are expensive and take months, if not years, to perform.  If a double-blind study is not mentioned in connection to a product it has not been performed.  So be wary of scientific claims and studies in connection to products.

University associations with products should be questioned as well.  Cosmedicine actually gave John Hopkins University stock in its company in exchange for using its name in advertisements.

And the words “dermatologist tested” are meaningless as well.  The FDA does not approve such language; once again this is simply a marketing strategy in order to lend more credence to a product.  A dermatologist could have simply picked up and looked at a product in order for a manufacturer to use such language in its marketing.

What about endorsements from fashion and beauty magazines?  I reviewed Lucky’s beauty editor’s book in this blog in order to better understand what beauty editors know about skincare.  Reading that book did not shake my feeling that beauty editors know little to nothing about actual skincare.  So how do they know which products to recommend?  Well according to Yarosh magazines are beholden to their advertisers and promote the products that will make the magazine money in the end with ad pages (Yarosh page 55).  So be very wary of product recommendations in magazines.

And what about the FDA’s role in protecting consumers?  When it comes to FDA supervision over skincare products there are a few regulations that companies have to follow – instructions on how to use a product needs to written on the box or container.  If the product you bought was a drug than it needs to include an insert with very detailed instructions on how it works, potential side effects, and contraindications.  Unless the manufacturer is making really outrageous claims about their product the FDA rarely steps in.  This isn’t the case in other countries.  Take the UK for example:

In the U.K., advertising is regulated through the independent body Advertising Standards Authority (ASA), which, in the past two years, has become much more active in scrutinizing cosmetics. The type of claim a brand can make in the U.K. is “softer” than elsewhere. For example, a skin care brand can claim to reduce wrinkles in U.S. advertising, but in the U.K., it must talk about reducing “the appearance of” wrinkles.

“Claims are the same, in principle,” said Chris Gummer, director of U.K. consultancy Cider Solutions Ltd. “It doesn’t stop a brand making global claims. The ‘rule’ is that if you can say it in the U.K., you can say it anywhere.”

However, brands must also be aware of what they imply. For example, L’Oréal Paris was reprimanded by the ASA for its Telescopic Mascara advertisement, which implied that spokesmodel Penelope Cruz had created her implausibly long lashes by using the product. L’Oréal admitted she was wearing false eyelashes in the TV and print ads, and the company was forced to include a disclaimer in future campaigns. These days, skin care brands go to great lengths to superimpose text onto U.K. ads to ensure they meet the ASA’s stringent criteria.

Gummer points out that although it may seem easier to make claims on the U.S. market, brands still need to have data to support what they say, and marketers remain responsible for juggling claims and where they are made. “Until other countries have similar controls as the U.K., then there will be different claims for products,” affirms Skinnovation’s Ferguson.  (From Skin Inc.’s article Justifying Skin Care Claims)


Case Study:  Dr. Perricone and His Products

In my opinion one of the biggest offenders in this world of hype and pseudoscience is Dr. Perricone who sells two skincare lines and a line of nutritional supplements while also writing many bestselling skincare information books.  If you read one of Dr. Perricone’s books or simply log on to his website you might think that you have found the cure for all that ails your skin (and perhaps even your overall health).  But stop!  Before you believe all that hype think of the following things.  (I am indebted to the website Quack Watch and their article A Skeptical View of the Perricone Prescription for the information about Dr. Perricone’s books and products):

Perricone‘s books are sprinkled with statements that his ideas are based on his own research. However, the extent and quality of this research is unclear. A PubMed search for his name brought up only six citations, of which only two appear to be original research, both on topical glycolic acid . His books describe situations in which he tested various ideas in a few patients, usually over a short period of time, but he provides few details and apparently published none of those findings in medical journals.

Dr. Perricone would be more credible if he could show us a study demonstrating that people who followed his prescription lived longer, had “younger” skin demonstrated by objective measures, or felt better compared to those on a placebo program—or that they were better in any measurable way. Instead, he provides only testimonials, exaggerated claims, partial truths, and incorrect statements. He cherry-picks possibly supportive studies from the literature and ignores contradictory studies. He cites lots of lab studies (in vitro or in animals), but few that demonstrate any clinical effects in humans. The diet he recommends is low in calories, and weight loss alone may improve the way his patients look and feel. His advice about tobacco and sunscreens is appropriate, but there is little science behind the rest of his program. He seems to have gathered every nutrient and skin cream he had any reason to hypothesize might work and advised using all of them. A more rational approach would have been to first see which ones really worked, and later to see if any combinations of the effective agents worked better than a single agent. No scientist worth his salt does experiments without controls; Perricone treats everyone, so that there is no basis for comparison.

Dr. Perricone has mixed a pinch of science with a gallon of imagination to create an elaborate, time-consuming, expensive, prescription for a healthy life and younger skin. There is no reason to think his program is more effective than standard measures. Although some of his advice is standard, most of his recommendations are based on speculation and fanciful interpretation of selected medical literature. He makes lots of money by convincing patients and consumers, but he hasn’t succeeded in convincing critical thinkers, doctors, scientists, or anyone who wants to see hard evidence. Perricone’s “prescription” isn’t science; it’s creative salesmanship.

So what can you do in order to protect yourself from false claims and promises when it comes to skincare products?  Education!  Keep learning, keep reading, and keep an open mind.  If it is too good to be true – it is.

Nutritional Supplements and Your Skin or Eating Your Way to Better Skin October 20, 2010

I’ve been debating a long time about how to approach this subject on my blog.  Though I definitely think that the subject needs to addressed I’ve never been quite sure how to approach it mainly because the scope of the subject is so large.   But I finally decided that it is time to take the plunge and write this post.

There are quite a few things that need to be mentioned here.  One is the issue of a healthy diet and how to affects your skin.  Another entirely separate issue is that of supplements, in pill form or drink form, that claim to address all sorts of skin issues from acne to aging.   I actually already wrote two posts debunking the idea that you can drink collagen in order to get smoother skin (see my posts Can You Drink Your Way to Firmer Skin?  and Taste Test) and have even addressed the issue of diet and acne in an earlier post, but I felt it was time to delve a bit deeper into the issue.


Healthy Diet = Healthy Skin?


Everyone of us already knows that in order to stay healthy we should, ideally follow, a healthy diet.  At the very least we should reduce our intake of fast food, fatty foods, and excessive amounts of sugar and processed foods.  So if we follow a healthy diet will this be reflected in our skin?  Many experts would say yes.  But just what are we supposed to eat in order to maintain a youthful glow?  Well that opens up a lot of room for debate.   One of the biggest advocates for eating a certain diet in order to get and then maintain beautiful skin is Dr. Perricone.  His books are widely available if you want to check out his ideas and food plans. 

In an article for her Beauty Bulletin – The Best Foods for Beautiful Skin – Paula Begoun recommends eating berries, salmon, walnuts, whole grains, and yogurt (among other foods) in order to maintain healthy skin.  Much of that advice is reflected in Chapter 4: Beauty and The Buffet of celebrity esthetician Kate Somerville’s book Complexion Perfection!.  Somerville, like Begoun, tells her readers to eat salmon, whole grains, and berries.  Additionally, Somerville also recommends eating black beans, almonds, flaxseed, and sweet potatoes (plus other foods).  A one day sample menu for healthy eating is even provided in her book.

But my favorite advice about diet and your skin comes from Dr. Amy Wechsler’s wonderful book The Mind Beauty Connection.  (I highly recommend this book if you want to better understand how stress and lifestyle choices affect your skin)  Chapter 7 of the book is entitled The Beauty Buffet and Bar: Optimum Diet Choices for Beautiful Skin, and the chapter does an excellent job in explaining why certain foods may positively impact the appearance of your skin and how a healthy diet can help the health of your skin.  While rereading this chapter of Wechsler’s book for the writing of this post I was struck by both the logic and insight of what she wrote time and again.   I think it is a good idea to share some quotes from the above mentioned chapter (pages 167-169): 

There is no magic pill, potion, formula for beauty.  Too many things coalesce in our bodies to produce either the results we want or don’t want. … There is … plenty of scientific proof about eating certain foods to support your skin and health, while avoiding others that can sabotage your beauty goals.  Don’t panic:  The point is not for you to do anything too unrealistic, such as suddenly savor wheatgrass juice or spoon flaxseed oil in your mouth every morning.  …  Remember, this isn’t about going on a specific diet.  It’s ultimately up to you to make modifications in how you eat so you can move over to a lifetime of healthy eating – and limitless beauty.  As with any healthy eating guidelines, the goal here is to supply your cells and systems with the raw materials they need to function efficiently and optimally, inside and out.  You don’t want to give your body any excuse to age prematurely, so you need to be sure that at any given time it has all the resources it requires to stay alive, hydrated, and nourished to the max. 

Nutritional medicine is a rapidly growing area of research that will continue to gain momentum as we learn more and more about the connections between nutrition and health – not just in relation to skin health, but all kinds of health concerns.  In fact, the link between nutrition and diseases like obesity, diabetes, cancer, and cardiovascular disease are well documented.  I expect us to learn more and more about the powerful influences diet can have on our skin health and ability to slow down the inevitable decline we call aging and its appearance on our bodies.  Because we know that oxidative stress, inflammation, and, to a lesser extent, genetics, are the chief agers in our bodies, and because they spur chronic conditions that wear us down physically, gaining the upper hand on these as best we can is key.  And if diet can help this in any way, then we should be paying attention.

I also want to note that there is no single approach to optimizing health and beauty, and that diet alone is not the answer.  …  The combination of proven skin-care techniques, relaxation therapies to dampen stress, exercise, restful sleep, and diet are all important and play a part in your looks on the inside and the outside.  It would be impossible to say which of these factors is more important than the other.  They all bear weight, and perhaps which one carries the most depends on the individual, especially as they relate to a person’s genetics and other lifestyle choices.


Like Begoun and Somerville, Dr. Wechsler also recommends eating berries, nuts, and salmon, among other foods.  (I am starting to sense a theme here)  Furthermore, Dr. Wechsler is a big advocate of drinking lots of green tea throughout the day and taking a multivitamin.


What About Nutritional Supplements?


More than one well-known skincare expert/source sells nutritional supplements than claim, as already mentioned, to clear your skin or prevent aging.  To name just a few, you can buy supplements from Perricone MD , Murad, and Kate Somerville.  (As an esthetician I do not recommend a certain diet or any supplements to my clients.  That is an area that is well outside my expertise.  If a client does ask me about such issues I recommend that they look at Dr. Perricone’s books or Dr. Wechsler’s book and leave the final decision on what to do up to the individual.)  It definitely is alluring to think that all you need to do is pop a few pills a day, recommended by a skincare expert no less, in order to look beautiful.  Yet let me debunk that idea.  Once again I’ll quote from The Mind Beauty Connection (page 194):

 The Truth About Vitamin C and E Supplements and Skin Vitamins:

What about individual nutrients or special skin-health formulas that claim to improve skin?  These grab-bag concoctions, which are mostly a mix of antioxidants, are hugely popular.  However, there’s minimal proof of payoff, at least right now.  Oodles of isolated antioxidants like vitamins C and E and phyto-chemicals like those found in green tea have been dazzling in the test tube.  When fed to lab animals, they have been marvelous at protecting against sun damage, wrinkles, and cancer; making skin softer, moister, and smoother; and halting inflammation and signs of agin.  Those effects almost disappear when single-nutrient pills are tested in people.  Green tea polyphenol pills, for example, protect mice skin from UV damage and skin cancer but do nada for human skin.  In a topic form, however green tea is anti-inflammatory and photoprotective.

In fact, studies of isolated antioxidant pills in humans have overall been not only disappointing but actually worrisome.  Disappointing because the supplements haven’t staved off health trouble.  Worrisome because studies have shown that people with various diseases, from heart problems to liver aliments, who took vitamins A, E, and/or beta-carotene supplements, either to try and stop the disease or keep it from coming back, had a greater risk of dying than those who didn’t.

Punch line: The more research we do on antioxidants, the more it looks like the work best in our bodies when they are consumed with other vitamins, minerals, and probably other components we haven’t even discovered yet.  All of the antioxidants nutrients you need come packaged together whenever you eat a stalk of broccoli or a juicy plum or a slice of multigrain walnut- raisin bread.  Put simply:  Eat whole foods.


Need further proof?  During the months I was contemplating how to write this post I came across a great article in the The New York Times by Alex Kuczynski called The Beauty-From-Within MarketKuczynski concisely addresses just these issues:  how Americans love the idea of nutritional supplements and if they really work:

Americans take pills to scrub our arteries, to relax us for airplane flights, to deforest our nasal passages of mucus and to remoisten our tear ducts. We take pills to sharpen our memory, to forget the awful things that have happened to us, to revitalize our libidos and to fall into a stuporous, amnesiac, refrigerator-clearing sleep.

Like children wishing for magical results in a fairy tale, we can now also take pills to make us pretty. These are supplements sold at yoga studios, department stores, hair salons, some dermatology offices and even on QVC; they promise to even skin tone, reduce lines and wrinkles, shrink pores and offer protection from the sun. Along with food and drink that promote external beauty, these are part of what is known as the beauty-from-within industry, and it’s growing fast.  …

The global beauty-from-within market – comprising beauty foods, beverages and oral beauty supplements – totaled $5.9 billion in 2008 and $6.3 billion in 2009, and is projected to be up to $6.8 billion in 2010, according to Datamonitor, a market research company that studies the skin care market. (To compare, the global skin care market – which includes cleaners, moisturizers and anything you apply to the surface of your skin — is projected to reach $65.7 billion in 2010.)


Kuczynski tried the supplement Glisodin and didn’t see much of result with her skin.  She also interviewed two experts for her article (of course when I saw that one of the experts interviewed was Dr. Wechsler I was very happy):

Marion Nestle, a professor of nutrition, food studies and public health at New York University… is the queen of skepticism on the purported beauty benefits of supplements. “Lecture time,” Nestle said. “If you eat any kind of reasonable diet you will not have deficiencies that can be addressed by vitamins. All you are going to do is pee them out.”

The irony, she said, is that people who have little need for supplementary vitamins and minerals are the ones most predisposed to take them. “People with disposable income to spend on vitamins, who are interested in their health and well-being, these are the people who need them the least,” she said. And people who care about their skin enough to take beauty vitamins are also probably wearing sunscreen and using moisturizer. “It is very hard to demonstrate health in people who are already healthy,” she said. And it is also difficult to gauge improved dermatological health in people who already practice good skin habits.

The chief problem with beauty supplements,  said [Dr. Amy Wechsler, a dermatologist in Manhattan], is that no matter how effective the delivery system, very little nutrients can reach the skin from a pill. In other words, my skin wasn’t going to look as poreless and pure … Lady Gaga’s, just from popping a pill.

“It is very American to put hope in a bottle,” Wechsler said. “And it is also very American to try to sell that hope.”


Bottom Line:  Eat a healthy diet, destress, and practice good skincare habits and routines.   Don’t expect great changes from a pill.

Is Your Diet Causing Your Acne? January 25, 2010

Filed under: Acne,beauty,Recommended Reading — askanesthetician @ 7:52 pm

One of the more controversial issues surrounding the causes of acne is the role diet plays in triggering acne.  Experts’ opinions on the subject vary tremendously and are also very polarizing.  For example in her book Rx for Brown Skin Dr. Susan Taylor writes: “Although many women believe that certain foods contribute to their acne outbreaks, there’s no evidence that food contributes to acne.  So the good news is that fried foods, greasy foods, chocolate, soda, and candy do not cause acne!” (p. 173).  Furthermore, Dr. Taylor writes that if you notice breakouts after you eat certain foods you shouldn’t jump to the conclusion that the foods triggered the acne.  Instead she points out: “the foods you may tend to eat when you’re stressed – sugary or greasy comfort foods – are probably just coincidental.”  (p. 174)  The acne that you see after eating sugary or greasy foods is related to  hormonal changes brought on by stress and not by the foods, Dr. Taylor concludes.

Dr. Doris J. Day takes a similar approach to Dr. Taylor in regards to foods as an acne trigger.  While Dr. Day writes in her book 100 Questions and Answers about Acne that “there is no scientific evidence available to show that high-carbohydrate and/or fat intake has any effect on sebum production or acne” (p.45) she does point out that there might be an explanation to the long held idea that diary can make acne worse.  Dr. Day explains that the hormones that are naturally found in the milk of cows, particularly pregnant cows which produce between 75% to 90% of the milk sold in stores, could play a role in acne formation (p.45).  Further, Dr. Day does suggest that eliminating certain foods from your diet that you deem are acne triggers is ok as long as those foods do not affect your overall health.  Dr. Day will concede that there is one ingredient that, if consumed in large enough quantities, can trigger acne.  That ingredient is iodine.

At the complete opposite spectrum is the advice of dermatologist Dr. Nicholas Perricone.  As outlined in his best-selling book The Clear Skin Prescription and on his website Dr. Perricone promises a flawless complexion, in only four weeks, if one is to follow his anti-inflammation diet, take the supplements he recommends (which he conveniently sells for a very high price on his website), and use the topical treatments he recommends.  Why is Dr. Perricone so convinced that food does make a significant difference in the appearance of one’s skin and in the formation of acne?  Because Dr. Perricone believes that all acne is inflammatory acne and that a diet that combats inflammation will positively affect acne, i.e. stop acne from occurring in the first place. 

How exactly does the inflammation trigger acne?  Acne begins to form when pores become clogged with dead cells that have not been properly removed.  In his book Dr. Perricone writes that an increase in blood sugar causes retention hyperkeratosis or the retention of and sticking together of dead cells in the pores.  This same increase in blood sugar causes inflammation on a cellular level and can even increase sebum production in the sebaceous glands.  The inflammation continues working on a molecular level in the cells, and causes the sebaceous cells to secrete proinflammatory fatty acids.  The crux of Dr. Perricone’s reasoning for following his anti-inflammatory diet is that by reducing the inflammation on a cellular level through the foods we eat will radically affect existing acne and prevent future breakouts.

Dr. Perricone writes that the foods one eats as well as the foods one avoids are equally important.  Dr. Perricone explains that one needs to carefully regulate their blood sugar level in order to have clear, healthy skin.  A rapid rise in blood sugar levels makes the body create insulin which then causes the body to have an inflammatory response.  More insulin equals more inflammation equals more acne, according to Dr. Perricone.  Sweets are certainly rapidly converted to sugars in the body but so are simple starches such as bananas, potatoes, corn, and peas – to name a few.  When you eat these foods your body experiences a rapid rise in blood sugar, which triggers an increase in insulin, and then inflammation on a cellular level (p.57).  In addition to avoiding foods that trigger that above mentioned responses it is important, according to Dr. Perricone, to integrate anti-inflammatory foods into one’s diet.  These foods are usually high in essential fatty acids.  He particularly advocates eating a lot of wild Alaskan salmon, fresh berries and melon, and drinking lots of water ( p.59). 

Dr. Perricone is only one of a few experts who see a direct connection between food and acne.  Certainly his argument does make some sense and the before and after photos in his book are dramatic and intriguing, but if Dr. Perricone is so right about the role diet plays in the formation of acne why do more experts not agree with him?  In my opinion, Dr. Perricone’s advice is certainly another acne solution to consider especially if one is inclined to seek more natural solutions for health issues as opposed to prescription solutions or if one has tried numerous options and has yet to experience relief from acne breakouts.  Yet for Dr. Perricone’s advise to be taken more seriously more studies have to be done that are independent of his own research.  It will be interesting to see what research about the connection between acne and diet reveals in the future.


 UPDATE:  Since I wrote this post I’ve reconsidered the idea of how diet impacts acne.  See my post Book Review:  The Clear Skin Diet for more information.
