Skin Whitening and Anti-Aging Claims: When a Cosmetic Becomes a Drug

The short answer

In the US, a cosmetic changes how you look; a drug changes how your body works. Skincare claims that cross that line — lightening skin, reducing melanin, regenerating cells, regrowing hair — make the product a drug, with very different rules.

Claims FDA treats as drug claims

FDA's own examples of claims that make a product a drug include claims to:

• increase or decrease the production of melanin (skin lightening or darkening);
• regenerate cells;
• restore hair growth;
• reduce cellulite or treat varicose veins.

Safer wording vs risky wording

Hydroquinone: not allowed over the counter

FDA says that, since the CARES Act took effect, over-the-counter skin lightening products containing hydroquinone are unapproved new drugs. They had to be removed from the market from September 23, 2020, and now need an approved new drug application. In 2022 FDA sent warning letters to 12 companies selling such products. FDA also warns consumers about skin products containing mercury.

What if my product really is a drug?

Then it must follow drug rules: an OTC monograph (where one fits) or an approved application, drug establishment registration, drug listing with an NDC, Drug Facts labeling and drug manufacturing standards. For many whitening and anti-aging actives, no OTC route exists — so the realistic choice is to sell a cosmetic with appearance claims only.

What FDA does — and does not do — for cosmetics

FDA does not approve cosmetic products or their labels before they are sold (color additives are the exception). Registration and listing are not an approval, so never write “FDA approved” or “FDA certified” on a cosmetic label or website. Under MoCRA, the brand carries the responsibility: it must be able to show the product is safe as used, and FDA can inspect records, ask for safety information and, in serious cases, suspend a facility's registration or order a recall.

At the US border, FDA reviews imported cosmetics and can detain a shipment that appears adulterated or misbranded — for example a wrong or missing English label, an unapproved color, a prohibited ingredient or drug claims. Detained goods must be brought into compliance, exported or destroyed, so it pays to fix problems before the first shipment.

Small businesses: what MoCRA exempts

MoCRA exempts certain small businesses from facility registration, product listing and GMP. The exemption does not cover products that regularly touch the eye's mucous membrane, injected products, products for internal use, or products meant to change appearance for more than 24 hours. Labeling, safety substantiation and adverse event reporting are not on the exempt list — and many US retailers and marketplaces ask for registration and listing anyway.

Step by step: selling your skincare in the US

3. 3List every productThe Responsible Person lists each product with its ingredients and updates the listing every year.
4. 4Make the label US-readyEnglish text, ingredient list, warnings, contact for adverse events — and the product-specific points above.
5. 5Keep safety records and an adverse event processSafety substantiation on file; serious adverse events reported within 15 business days.

Frequently asked questions

Can I sell a skin whitening cream in the US?

Not as a cosmetic if it claims to lighten skin by changing melanin — that is a drug claim. Over-the-counter hydroquinone skin lighteners cannot be legally marketed in the US: since September 23, 2020 they need an approved new drug application.

Is “brightening” a drug claim?

It depends on how it is used. “Brightens the look of skin” or “gives a radiant appearance” describes appearance and is usually cosmetic. “Reduces melanin”, “removes dark spots” or “treats pigmentation” are drug claims.

Are anti-aging claims allowed for cosmetics?

Claims about appearance — “reduces the look of fine lines” — are generally cosmetic. Claims that a product regenerates cells, boosts collagen production or changes skin structure are drug claims.

Does it matter what I say on Amazon or my website?

Yes. FDA looks at intended use shown in all labeling and marketing, including websites, marketplace listings and social media — not just the package.

Who is the Responsible Person under MoCRA?

The manufacturer, packer or distributor whose name appears on the label. The Responsible Person lists the products, keeps safety records and reports serious adverse events to FDA within 15 business days.

Are small cosmetic businesses exempt from MoCRA?

Certain small businesses are exempt from facility registration, product listing and GMP — but not for products that touch the eye’s mucous membrane, injected products, products for internal use or products that change appearance for more than 24 hours. Labeling, safety records and adverse event reporting still apply.
