Understanding the ingredients listed in the ingredient list of a skincare product and figuring out if those ingredients are actually effective for your skin is an important skill for skincare consumers to have. But interpreting a skincare ingredient label is not easy by any stretch of the imagination. You need to not only have some basic skincare product formulation knowledge but also be able to recognize different ingredients and their function in skincare products in order to understand what you are reading and if the product will be right for your skin and will do what it claims to do. I’ve addressed this topic in the past here in my blog, but lately I’ve come across a few interesting articles on the subject and thought it was time to revisit this issue much more in-depth than I did before.
The Basics and Some Examples
There are basic rules that product manufacturers must comply with in order to list ingredients on their products.
- Standardized names. Ingredient names must comply with the International Nomenclature for Cosmetic Ingredients (INCI) format. The ingredient names are standardized in this format so that all products can be compared to each other easily and for safety reasons.
- Descending order. Ingredients must be listed in descending order of concentration to 1%. Ingredients below 1% can be listed in any order
How does this come together for the consumer? Lab Muffin recently published yet another excellent post called How to Read an Ingredients List: Face Moisturisers in which she takes actual moisturizer labels and explains the ingredients for her readers. For instance:
When looking at most product ingredients lists, the ingredients will be in order from the highest concentration to the lowest. Typically, when deciding if a moisturiser will suit your skin type, you don’t need to look past the first 6 ingredients or so, since they make up the majority of the product, and will be responsible for the moisturising action. It’s a different story when you’re looking at more potent ingredients that target specific concerns (e.g. anti-aging, exfoliants, antibacterials, lightening), but those tend to be useful regardless of skin type.
With this in mind, I’ll be classifying the top 6 ingredients in each of these facial moisturisers, as well as commenting on some of the notable ingredients further down in the list. If there’s no comment next to the ingredient, I’ve probably explained it in a product further up.
To recap, the main categories of moisturiser are:
Occlusives - block water from evaporating from the skin, especially good for dry and dehydrated skin
Emollients - smooth skin and help repair
Humectants - draw moisture to the skin, effective even at lower percentages.
Jurlique Calendula Redness Rescue Soothing Moisturising Cream
Aqua (water) – The base for most face creams, and the definition of moisture.
Cetearyl alcohol (emollient) – A blend of cetyl and stearyl alcohols, two fatty alcohols that are nothing like drinking alcohol (that is, ethyl alcohol), but are great for smoothing skin down as well as making sure the oily and watery parts of the moisturiser don’t separate (it’s an emulsifier). It can be derived from coconut oil.
Rosa canina fruit oil (emollient) – This is the technical name for rose hip oil from a specific species of rose. It mainly contains oleic and linoleic acids, which are excellent for repairing skin, as well as antioxidants.
Safflower seed oil (emollient/occlusive) – This also contains many linoleic acids and antioxidants.
Caprylic/capric triglyceride (emollient/occlusive) – This also comes from coconut oil, and smooths skin as well as blocks evaporation.
Jojoba seed oil (emollient) – This stuff is a lot like natural sebum.
Glycerin and honey are a little further down in the list, and there’s aloe vera extract as well – these humectants together would probably add noticeable humectant action to the mix (glycerin is typically used in moisturisers at 2-7%, otherwise it feels sticky).
Overall: Lots of emollients, a small amount of occlusives and some humectants. It’s suitable for all skin due to all the skin-repairing emollients, but drier skins might need some more occlusives on top.
Or for example how to interpret a serum label:
Generally, serums are used to deliver active ingredients to skin in higher concentrations in order to generate a specific skin response. Typical serums address skin-specific issues, such as hyperpigmentation, lines and wrinkles, sagging skin, texture, tone, pore size, acne, redness and irritation.
Understanding ingredient listings in serums is often difficult. Active ingredient names can take the form of Latin names for botanically sourced compounds, and more generic INCI names may be used, such as yeast extract, which can mean a multitude of biologically active ingredients. Quite long chemical names are often found.
Understanding the dose of active ingredients is also difficult by trying to interpret ingredient listings. If a particularly active ingredient is very biologically active, it may be dosed in the formula in part-per-million levels and be very low in the ingredient listing, but still be quite effective. Examples of these are epigenetic factors, epidermal growth factors and vascular growth factors.
1. There are more than 16,000 listings in the INCI dictionary. No one can know all the cosmetic ingredients at any given time. If you are unsure what dose and what active ingredient is in particular serum, request that the manufacturer supply that detailed information.
2. Watch out for serum claims and their target biology. For example, if you have a serum that claims it can improve collagen and elastin by stimulating skin, the ingredient would need to penetrate to the dermal tissue. If you need to lighten skin, ingredients must penetrate no more than to the epidermal-dermal junction, where color-producing cells exist. If you want to exfoliate, the serum should not penetrate far below the stratum corneum.

Putting It Together
Now that you have some basic knowledge about how skincare labels work is this really enough information in order to know if a product is right for your skin or not? Sorry to complicate things for you, but even the most savvy consumer can get tripped up by a skincare ingredient label. Renee Rouleau gives a great example in her blog post Can You Judge a Skin Care Product by an Ingredient Label?:
With so much awareness on skin care ingredients (the good, the bad and the ugly), consumers now more than ever are getting educated on what’s used in formulas, so they can make the best choices for their skin when it comes to choosing products to apply to their face. But by looking at an ingredient list on the back of a bottle or jar, can you really determine if it will deliver good results or not on your skin?
The answer is no. You might look at the ingredient list and form assumptions about the ingredients you may have read about or heard of. For example, if you’re prone to breakouts you might see shea butter or sunflower oil listed, and assume it will be greasy and pore clogging. These assumptions can be invalid, because the results a product delivers are based on the percentages of the ingredient used in a product—and this, you’ll never know from looking at the list on the back of a bottle.
Here’s another example of a time when one of my products, Daily Protection SPF 30, was reviewed by a fairly well-known ingredient expert who has written many books on helping you choose the best products when you go to the cosmetics counter. She had requested the ingredient list of my sunscreen to review, yet didn’t request the actual product. When the review was published, she gave it a really good review however, she said based on the moisturizing agents used in the formula, it was best suited for dry and very dry skin types. Really? Our Daily Protection SPF 30 is recommended for oily, acne-prone skin, because it is so light, and dries to a matte finish on the skin. As a matter of fact, when we get a customer return for this product, it’s usually a dry skin client saying it was too drying on their skin. Our oily skin clients absolutely love it because it disappears completely and leaves no residue. This is definitely not a sunscreen moisturizer for dry and very dry skin types, yet an ingredient label reviewed by an ingredient expert couldn’t tell this. (No disrespect to the expert, this is simply my experience.)

So Where Does That Leave You?
It is important to learn about ingredients and how skincare products are formulated in order to be an educated skincare consumer. The more you know the better choices you can make for your skin, and you can save yourself time and money from buying the wrong products. Part of that education is learning to read a skincare label instead of just blindly believing the manufacturers’ hype and marketing campaign. But don’t let the skincare label be your be all or end all in order to know if a skincare product is right for you. Try products first before rebuffing them. Ask for samples and find online reviews from people who have actually tried the product before rejecting a product based just on reading the ingredient list or taking advice from someone who reviews products only according to their ingredient list. Two websites that I like for product reviews combine both information about the products’ ingredients and actually try the products themselves before writing a review. Those websites are FutureDerm and Lab Muffin.
