Cosmetic claims vs drug claims in creator videos

Last checked against the sources below: October 20, 2026. Watchword re-checks these sources every week. This page summarizes FDA’s public guidance, FDA warning letters, a federal regulation and TikTok Shop’s US seller policies. It is not legal advice.

A skincare product can be a cosmetic, a drug, or both, and under FDA’s guidance the deciding factor is the product’s intended use, which can be shown by the claims made about it. This page sets out, from FDA’s and TikTok Shop’s own pages, which kinds of claims FDA treats as drug claims, what FDA warning letters show about social media posts, and what TikTok Shop’s beauty rules add. Whether a specific claim, product or video crosses the line is a question for counsel.

The short answer. FDA says whether a product is a cosmetic or a drug “is determined by a product’s intended use.” Claims about cleansing, beautifying or making lines “less noticeable” by moisturizing are cosmetic-type claims. Claims to treat disease or affect the structure or function of the skin, such as restoring hair growth, increasing collagen or decreasing melanin, are drug-type claims. FDA lists claims “in advertising, on the Internet, or in other promotional materials” as evidence of intended use, and its warning letters have quoted companies’ own Instagram posts.

How FDA decides: intended use

Two definitions. FDA quotes the law’s definition of cosmetics as articles applied to the body “for cleansing, beautifying, promoting attractiveness, or altering the appearance.” Drugs include articles “intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease” and articles “intended to affect the structure or any function of the body.”
Intended use decides. FDA says: “Whether a product is a cosmetic or a drug under the law is determined by a product’s intended use.”
Claims are evidence. FDA lists “Claims stated on the product labeling, in advertising, on the Internet, or in other promotional materials” as one way intended use is established, along with consumer perception and ingredients with a well-known therapeutic use.
Statements by representatives. The regulation at 21 CFR 201.128 says intent “may, for example, be shown by labeling claims, advertising matter, or oral or written statements by such persons or their representatives.”
No “cosmeceutical” category. FDA says the term “cosmeceutical” has no meaning under the law. A product is a drug, a cosmetic, or both.
Both at once. FDA’s examples of products that are both include antidandruff shampoo, antiperspirant deodorants, and moisturizers and makeup with sun-protection claims. These must meet the requirements for both cosmetics and drugs.

Cosmetic-type claims vs drug-type claims

FDA does not keep a list of approved cosmetic claims. Its own pages give these examples:

Claim	How FDA describes it
Moisturizing	“moisturizing is a cosmetic claim”
Making lines and wrinkles less noticeable by moisturizing	Cosmetic
Makeup or primer that hides signs of aging	Cosmetic
Removing wrinkles or increasing collagen production	“a drug or a medical device”
Restoring hair growth	Drug-type claim
Reducing cellulite or regenerating cells	Drug-type claim
Increasing or decreasing melanin production	Drug-type claim
Treating acne	Acne medications are an over-the-counter drug category
Treating dandruff	Makes an antidandruff shampoo both a cosmetic and a drug

FDA’s anti-aging page puts the line this way: products intended to affect the structure or function of the skin “are drugs, or sometimes medical devices, even if they affect the appearance.”

What FDA warning letters show about social media

FDA’s guidance does not use the words “social media.” Its warning letters do quote social posts as evidence of intended use. In the letters below, the posts were on the companies’ own accounts.

Matte Beauty, July 25, 2024. FDA quoted the company’s Instagram, including a post saying chemical peels “help skin disorders like acne and rosacea” and a post about increasing “collagen production,” and found the peels to be “unapproved new drugs.”
Dermal Source, March 25, 2024 (numbing products used before tattooing). FDA cited claims on the company’s website and “your social media account on Instagram” as evidence of intended use “(as defined in 21 CFR 201.128).” One quoted post is written in the first person by a tattoo artist. The letter attributes it to the company’s account and does not say who wrote it.
Glow Nest Beauty, March 3, 2025 (injectable fat-dissolving products). FDA quoted a dated Instagram post claiming a product “Promotes skin regeneration.”
Umbrella Labs, May 18, 2021. This is a supplement case, not a beauty case. FDA treated customer comments the company had “liked” on its posts as testimonials “endorsed or promoted” by the company.
Alwinshop, June 17, 2026. FDA reviewed a TikTok Shop storefront and quoted its listing text, including “Treatment for Prostatitis Symptom Relief.” The product is a topical cream, not a cosmetic.

We searched FDA’s warning letter database and did not find a letter to a beauty company that cites a paid creator’s or affiliate’s own post. That is a gap in the public record, not a statement that such posts are outside the rules. The regulation refers to statements by the responsible persons “or their representatives.” It does not say whether affiliate creators are representatives.

What TikTok Shop’s beauty rules add

TikTok Shop’s US “Beauty and Personal Care Products Requirements” (dated September 1, 2026) are a separate rule set from FDA’s. Among prohibited products, they list:

“Beauty and personal care products that claim to have medical applications but are not verified by the FDA”
“Beauty and personal care products that are not labeled correctly as both a cosmetic and a drug”
Products that aim to “bleach, whiten, lighten, or reduce overall melanin in the skin.” The same page says products “designed to enhance the complexion’s brightness, even skin tone, or reduce dark spots are permissible.”

TikTok’s line on dark spots is TikTok’s own rule. It is not the same test as FDA’s “increase or decrease the production of melanin” example, and one does not answer the other. TikTok Shop’s Product Listing Policy also prohibits “false, exaggerated, or unproven claims,” including misleading “before and after” images and claims to cure or manage a disease. Both pages are seller policies about listings. TikTok Shop’s general “Requirements for Responsible Health-Related Content” (dated September 2, 2026) says “Sellers and creators are responsible for complying” and that “Medical claims are prohibited for non-Over-the-Counter (non-OTC) products.”

What this means for a brand team

A brand can keep its labels and listings inside cosmetic claims and still see drug-type claims about its products in affiliate creator videos, such as “regrows hair,” “boosts collagen” or “clears acne.” FDA counts advertising and statements by a company’s representatives as evidence of intended use, without saying whether affiliate creators are representatives, and the FTC regulates advertising claims. In Watchword’s October 2026 study of 698 paid creator videos about 12 beauty brands on US TikTok, 116 (17%) made a drug-type claim about a product sold as a cosmetic. Knowing which creator videos about a product use drug-type language is the starting point for any conversation with counsel about it.

Common questions

What is the difference between a cosmetic claim and a drug claim?

FDA says the difference comes from intended use. Cosmetic claims are about cleansing, beautifying, promoting attractiveness or altering the appearance. Drug claims are about treating or preventing disease or affecting the structure or function of the body, including the skin, such as restoring hair growth or increasing collagen.

Can a social media post turn a cosmetic into a drug?

FDA lists claims “in advertising, on the Internet, or in other promotional materials” as evidence of a product’s intended use. FDA warning letters, including to Matte Beauty in 2024, have quoted companies’ own Instagram posts as evidence that products were drugs.

Is “anti-aging” a drug claim?

FDA says making lines and wrinkles less noticeable by moisturizing, or hiding signs of aging with makeup, is cosmetic. Claims to remove wrinkles or increase the skin’s collagen production are drug or device claims.

Does TikTok Shop allow skin lightening products?

TikTok Shop’s US beauty requirements prohibit products that aim to “bleach, whiten, lighten, or reduce overall melanin in the skin,” but say products designed to enhance brightness, even skin tone or reduce dark spots are permissible. That is TikTok’s rule, separate from FDA’s.

Has FDA cited an influencer’s post in a beauty warning letter?

We did not find one in FDA’s warning letter database as of October 20, 2026. The letters we found quote companies’ own social accounts. One supplement letter treated customer comments the company had “liked” as endorsed testimonials.
