“Treats acne”: the claim that turns your cosmetic into a drug
In the US, a product intended to treat or prevent acne — or any disease, or to affect the structure or function of the body — is a drug under FD&C Act §201(g), whatever its ingredients. The claim on the label decides, not the formula.
Short answer: in the US, a product that claims to treat or prevent acne is a drug under the Federal Food, Drug, and Cosmetic Act §201(g), regardless of its ingredients. “Treats acne,” “eliminates blemishes,” and similar statements are drug claims; “dries up pimples” belongs to the same family. The claim defines the product.
The test
| What the label says | Product category |
|---|---|
| “Cleanses skin”, “removes oil” | Cosmetic |
| “Improves the look of blemishes” | Cosmetic (appearance claim) |
| “Treats acne”, “prevents acne” | Drug |
| “Contains 2% salicylic acid acne medication” | Drug (OTC acne product) |
The legal test is intended use (FD&C Act §201(g)(1)(B)–(C)): products intended to treat or prevent disease, or to affect the structure or any function of the body, are drugs. Intent is established by the claims in labeling, advertising, and marketing materials — not by the ingredient list. Salicylic acid is a cosmetic ingredient in one product and an OTC drug ingredient in another, on the strength of the words around it.
Why it matters
A drug needs an approved application or compliance with an OTC monograph, drug-factory registration, drug listing, and drug labeling — none of which a cosmetic has. Marketing a cosmetic with drug claims is an unapproved drug on the market. This is one of the most common FDA warning-letter subjects for small skincare brands.
Common mistakes
- “Treats acne” in an Instagram caption or Amazon bullet point while the label itself says “cosmetic”. Claims anywhere in your marketing count.
- Borrowing claim language from an OTC benzoyl-peroxide wash for a cosmetic cleanser.
- Thinking a natural formula escapes the test. The test is the claim, not the ingredient source.
- Copying the EU label, where acne-related statements are judged differently, without re-reading every claim for US drug status.
