The short answer. Not reliably. A cosmetic ingredient list is not a formula sheet with percentages. In the United States, order gives some information about relative amounts, but there are exceptions and it does not reveal an exact concentration for every ingredient.
What does the US ordering rule actually say?
Under the FDA's cosmetic labeling rules, ingredients present at more than 1% are listed in descending order of predominance. Ingredients present at 1% or less may then follow in any order, and color additives have their own exception and may follow the other cosmetic ingredients in any order regardless of amount. Products that are both a cosmetic and a drug carry additional active-ingredient labeling, so a Drug Facts panel is not an ordinary cosmetic ingredient list and should not be read as one. FDA cosmetics labeling guide.
This is a brief, US-specific summary of the ordinary rule for a shopper's purposes, not legal or compliance advice, and other markets have their own labeling requirements.
What can you conclude from the list?
| Can conclude | Cannot conclude | Ask the brand |
|---|---|---|
| Among the ingredients above 1%, an earlier entry is present in the same or a larger amount than a later one | Its exact percentage | The exact product, version and market the list belongs to |
| Two ingredients may both sit at or below 1% if they appear after that point | Where the 1% line falls, because it is not marked on the label | Whether a claimed percentage refers to the pure ingredient or to a supplied blend that contains it |
| Which named ingredients the brand declares | A potency ranking, a comparison between two products' strengths, or a finished-product result | Whether the brand has evidence for any finished-product claim it makes |
A hypothetical label, read carefully
Imagine a US cosmetic list that reads: water, glycerin, a humectant, a thickener, a plant extract, a preservative, a second preservative, sodium hyaluronate. You can say that, among whichever entries are above 1%, each is present in the same or a larger amount than the one after it, so amounts do not increase as you read down that part of the list. You cannot say where the 1% line falls, so even the early entries are only known to lead if they are above it, and the plant extract might be above it or below it. You cannot say sodium hyaluronate is the smallest amount, because anything at 1% or less may be listed in any order. And nothing on the list tells you a percentage for any single entry.
That is why this page names no Baegayul percentages. Our own published ingredient information describes selected ingredients, and percentages should not be inferred from an ingredient highlights list.
