Here’s How to Read a List of Ingredients
Revealing the mystical language of the ingredient list: INCI, active ingredients, and more
Posted on December 5, 2019 Written by: 100% PURE ®Have you ever read the list of ingredients on your favorite beauty product and wondered what the names mean, or how much of each ingredient is included? When it comes to personal care products like makeup, skin care, and hair care, the ingredient lists are more or less a language all their own. The good news is that you can learn this language pretty quickly – we’ll show you how!
The fact that you’re reading this is a testament to how beauty enthusiasts have become more informed than ever when selecting the right product for their needs. Those purchasing skin care and makeup still care about results, but perhaps even more about what exactly what ingredients they’re applying on a daily basis.
In order to understand the list of ingredients on your product, it all starts with understanding the INCI.
The acronym INCI stands for “International Nomenclature Cosmetic Ingredient”. This is the standard by which cosmetic ingredients are named and categorized in the United States. INCI names are shown out of parentheses, and can be scientific names, Latin names, or English words.
Regulated by the Personal Care Products Council (PCPC), the INCI is the system of names given to cosmetic ingredients. This system helps to provide a sense of clarity, standard, and accuracy in the beauty industry – while helping to keep consumers informed.
The bottom line: INCI ensures that all ingredients are referred to by a specific name when listed on a product.

Oops! something went wrong.The INCI is important for cosmetic professionals because it allows dermatologists and scientists to identify the ingredients in a product. Based on a standard description and name, they can successfully document the effects of an ingredient in a way that members of the community can understand.
Chemists and formulators aren’t the only ones who need INCI; consumers can also better understand a product after reading the INCI. Rather than rely on what a company tells you in their marketing messaging, you can see for yourself if the product is worth it – by simply reading the ingredient list. Your understanding of the INCI will improve as you learn more about the most recurring ingredients.
That being said, it’s important to note that just because something is named by the INCI, it doesn’t guarantee an ingredient’s reputability or quality. The INCI exists purely to create a standard language, without causing any confusion. It also helps beauty experts (like us) know exactly what they don’t want in their formulas.
Another thing to know when reading a cosmetic list of ingredients: you’re looking at a two names for a single ingredient. For example, vitamin A and retinol are, for all intents and purposes, the same. However, “vitamin A” is considered this ingredient’s common name, whereas “Retinol” is the INCI name.
Other examples of INCI and common names on a list of ingredients include:
Common Name
Vitamin E
Cocoa Bean
Vitamin C
Green Tea Extract
Sweet Almond Oil
Grape Seed
INCI Name
Tocopherol
Theobroma Cacao
Ascorbic Acid
Camellia Sinensis Leaf Extract
Prunus Amygdalus Dulcis
Vitis Vinifera
Some personal care products, such as acne medications and sunscreens, are considered over-the-counter drugs. As such, the ingredients listed on these products will be categorized as either “active” or “inactive” ingredients.
This may sound confusing, at first: shouldn’t all of the ingredients be active in a product? Technically, yes, but in truth, some ingredients play a larger role than others.
Titanium dioxide, for instance, is always listed as an active ingredient in sunscreens because it plays a major role in protecting your skin from the sun, which is the central purpose of the product. Likewise, an acne treatment might list salicylic acid as an active ingredient, because its primary function is to eliminate acne.
Inactive ingredients, meanwhile, are ingredients that perform supporting functions, such as moisturizing the skin or decreasing the appearance of pores.
In the United States, the ingredient list is regulated by the FDA. As such, it follows a specific hierarchy of order: all ingredients that make up more than 1% of the product are listed first, and in order from highest to lowest. This means that the most abundant ingredient in the product should always be listed first.
Meanwhile, any ingredients under 1% can be listed in any order, with any dyes or colorants listed at the end.
Buyer beware: any added scent – even if there’s more than one – can be listed under the singular title “fragrance”. For those with skin sensitivities or allergies, this is important to note!
Hierarchy in a list of ingredients is broken down like this:
-
First Third of Ingredients: ~80% of the total formula
-
Second Third of Ingredients: ~15-19% of the total formula
-
Final Third of Ingredients: ~1-5% of the total formula
With this hierarchy in mind, you can begin to recognize the quality of certain products purely based off what’s listed and in what order. For instance, if a product endorses that it carries beneficial ingredients like tea tree and willow, you’d want to check the ingredient list and make sure that those plant-based goodies are listed near the top.
Similarly, if a product is advertised for a special ingredient and it’s listed last, you know that it’s heavily diluted. Especially one of the first ingredients is actually water, or a cheaper filler oil.
Water is often the second or third ingredient in products, indicating that it’s one of the most abundant ingredients in the product. Generally, these products are low-quality, and the benefits won’t be as concentrated.
Cosmetic companies will often try to get you to buy a product by slapping on glittering generalities like “natural”, “hypo-allergenic”, or “fragrance-free”. If you take a closer look at the list of ingredients, the contents might suggest otherwise.
For beauty products, the only thing regulated by the FDA is the ingredients and the way they’re listed. A company may find it easy to make bold claims, even if these claims may not even be true. Medicine/drug claims adhere to much stricter regulations, but for beauty products, we’d recommend flipping to the back of the bottle before believing any bold claims.
While the ingredient list on the back of your skin care products may appear intimidating at first glance, understanding their meaning is simply a matter of research. That is, understanding certain ingredients and why they appear more frequently than others, and how to gauge the amount used – and what it can mean for your skin or hair.
Rather than take beauty companies’ claims to heart – read the list of ingredients and make up your own mind!
