Beauty marketing claims in the US: why sunscreen changes the rules

FDA classification turns on intended use. Product names, packaging, websites, creator scripts, search ads, images, testimonials, and context can all contribute to that intended use, and language on the wrong side of the line can make a product a drug or both a drug and a cosmetic.

There is no magic list of safe beauty verbs: the entire context and the evidence still matter. Have regulatory counsel approve the actual claim system for the actual formula.

The FTC's current Health Products Compliance Guidance says advertisers need a reasonable basis for objective claims before dissemination and evaluates the express and implied messages conveyed by the ad as a whole. A small disclaimer cannot reliably reverse a prominent headline, image, testimonial, or demonstration that communicates a broader result; if a significant minority still takes away a misleading claim, the disclosure is not sufficient.

For health-related efficacy or safety claims, the FTC applies its rigorous competent-and-reliable-scientific-evidence standard and encourages review by an independent expert in the relevant field. Ingredient, animal, or in vitro research does not automatically prove a finished-product human claim, and a genuine customer testimonial does not replace substantiation. The evidence should match the formulation, population, use, dose, outcome, and strength of the message.

Sunscreen is regulated as an over-the-counter drug in the United States. A product marketed without an approved application must satisfy the current OTC sunscreen monograph and the other drug-side requirements summarized in the table above.

Do not assume a Korean sunscreen formula can be sold unchanged in the US because its SPF was tested or it is legal in Korea. Compare every active ingredient, concentration, dosage form, test, warning, claim, and label element against the live US pathway. The framework can change: FDA's June 9, 2026 final order added bemotrizinol, at concentrations up to 6%, to the OTC sunscreen monograph—the first new permitted sunscreen active ingredient since the late 1990s. That change does not automatically make a particular imported finished product compliant or approved.

A claims matrix is a controlled source of truth connecting each proposed message to its exact wording, product and variant, evidence, required qualifier, prohibited implication, owner, approval date, and permitted channels. It keeps the product page, marketplace listing, press copy, paid ads, affiliate brief, and customer service response from inventing different versions of the product truth.

Claims review should happen before packaging is printed, product pages are built, creators are contracted, or ads enter production. Late review creates reprints, rejected listings, unusable content, inventory delays, and inconsistent customer explanations.

Hypothetical example—not client work: a Korean SPF 50 cushion arrives with draft US copy promising 'waterproof protection all day' and creator footage repeating that line. Do not solve this with a smaller disclaimer. FDA treats products labeled with SPF as sunscreen drugs and its labeling rules do not permit 'waterproof' claims; the formula, pathway, finished-product tests, Drug Facts, use language, and water-resistance evidence need specialist review before the packaging or brief is approved.

Use a qualified US regulatory attorney or specialist for classification and claim approval. This article explains the operating problem; it is not legal or regulatory advice and does not determine whether any particular claim or product is compliant.
