Cosmetic, Drug, or Both? FDA Product Classification

Whether the FDA treats your product as a cosmetic, a drug, or both comes down to its intended use — not its ingredients, its packaging, or what you call it. That single classification decision drives everything that follows: whether you need FDA approval before selling, which manufacturing and labeling rules apply, and how much your compliance burden costs. Many products that look like ordinary cosmetics are legally drugs, and getting the call wrong invites warning letters, import refusals, and seizures.

Both categories are regulated under the Federal Food, Drug, and Cosmetic Act (FD&C Act), but they sit on very different tracks. Here is how the line is drawn.

How the FDA defines a cosmetic vs. a drug

The FD&C Act defines each category by intended use.

	Cosmetic — FD&C Act § 201(i)	Drug — FD&C Act § 201(g)
Intended use	Cleansing, beautifying, promoting attractiveness, or altering appearance	Diagnosing, curing, mitigating, treating, or preventing disease — or affecting the structure or function of the body
Examples	Skin cream, makeup, perfume, shampoo, nail polish	Acne treatment, antiperspirant, sunscreen, fluoride toothpaste
Premarket approval?	No FDA approval required (color additives are an exception)	Yes — a new drug application, or compliance with an OTC drug monograph

A cosmetic enhances appearance. A drug acts on the body to treat a condition or change how the body works. The same jar of lotion can be one or the other depending on what the maker claims it does.

It’s the intended use, not the ingredient

The FDA infers intended use from claims, labeling, consumer expectations, and even ingredients known to have a therapeutic effect. A few examples make the point:

A moisturizer is a cosmetic. Add a claim that it “reduces wrinkles by stimulating collagen”
