Cosmetic Claims and Marketing Rules

What you say about a beauty product is regulated as tightly as what goes in it. Two agencies police your marketing: the FDA polices the line between a cosmetic and a drug, and the FTC polices whether your claims are true. Cross either line and you invite warning letters, class-action lawsuits, and retailers pulling your product. The single most common way brands get in trouble is claiming their product does something to the body, which turns a cosmetic into an unapproved drug in the eyes of the law.

This is general educational information, not legal advice. If a specific claim is central to your brand, have a regulatory or advertising attorney review it before you run it.

The cosmetic-versus-drug line

This is the trap that catches the most brands, and it hinges entirely on your words, not your ingredients. By law, a cosmetic is something that cleanses or beautifies. The moment you claim a product treats or prevents a disease, or affects the structure or function of the body, it legally becomes a drug, which requires FDA approval you almost certainly do not have. The same serum can be a legal cosmetic or an illegal unapproved drug depending only on how you describe it.

Claims that push a product into drug territory include treating acne, healing eczema, “boosting collagen,” “stimulating cell renewal,” reducing wrinkles by changing the skin’s structure, or aromatherapy claims like helping someone sleep or quit smoking. The FDA has sent warning letters to major brands, including Avon and Lancôme, over anti-aging and anti-wrinkle claims that crossed this line.

The safe version describes appearance, not biology. “Moisturizes,” “softens the look of fine lines,” “adds radiance,” “temporarily plumps the look of skin,” and “minimizes the appearance of pores” are cosmetic claims. “Repairs,” “heals,” “regenerates,” and “boosts” are drug claims. When you write a claim, ask whether you are describing how the product makes skin look or what it does to the body. Looks is a cosmetic. Does is a drug.

The FTC rule: true, not misleading, and proven first

Separate from the FDA, the FTC requires that every claim be truthful, not misleading, and substantiated before you make it. For any objective or performance claim, you need adequate evidence in hand first, and for health or efficacy claims that means competent and reliable scientific evidence. “Clinically proven,” “reduces wrinkles by 50%,” and “dermatologist recommended” all require real proof you already hold. You cannot make the claim and hope to back it up later, and a pile of happy customer reviews does not count as scientific evidence.

The buzzwords that get brands sued

Several popular marketing words have no legal definition, which is exactly why they create liability. If a word implies something untrue about your product, it does not matter that the word itself is vague.

“Natural” and “clean.” Neither has an FDA or legal definition, so they mean whatever a customer assumes, and that gap is where lawsuits live. “Natural” claims have driven a wave of class-action suits when the product contained synthetic ingredients a reasonable shopper would not expect.

“Chemical-free.” This one is literally false, since everything, including water, is a chemical. It is a magnet for challenges and worth cutting from your vocabulary entirely.

“Organic.” The FDA does not define organic for cosmetics, but using the word can pull you under the USDA’s National Organic Program for agricultural ingredients and under state laws like the California Organic Products Act. Do not use it loosely.

“Hypoallergenic,” “dermatologist-tested,” and “non-comedogenic.” None are defined or verified by the FDA. You can use them, but you still cannot be misleading and you need to be able to back up what they imply.

“Cruelty-free” and “vegan.” No legal definition here either, and the FTC can act if the use is misleading. Third-party certification, like Leaping Bunny for cruelty-free, is how brands make these claims credible.

“FDA-approved.” Cosmetics are not approved by the FDA. Saying your cosmetic is FDA-approved is false and illegal, full stop.

Testimonials, influencers, and before-and-afters

The FTC’s endorsement rules govern how you use other people’s words. Any material connection between you and someone endorsing your product, meaning payment, free product, an affiliate commission, or an employment relationship, must be clearly and conspicuously disclosed. An influencer has to make that disclosure obvious, not buried in a wall of hashtags. A customer testimonial is not scientific proof of anything, and it cannot imply a typical result you are unable to substantiate. Before-and-after photos have to be honest and representative of what a normal customer can expect.

What it costs to get it wrong

The consequences stack up. The FDA issues public warning letters that force you to relabel or reformulate. The FTC can bring enforcement actions with fines and injunctions. Plaintiffs’ lawyers file class-action suits, especially over “natural” and similar claims. And retailers like Sephora and Ulta review the claims on the products they carry and will reject or pull a brand whose marketing creates legal risk. On top of all of it, MoCRA now legally requires you to substantiate the safety of every product, so your files need to be in order regardless.

How to stay on the right side

Describe how the product makes skin or hair look, not what it does to the body. Gather your evidence before you publish a performance claim, not after. Skip the undefined buzzwords, or back them with real third-party certification. Never call a cosmetic “FDA-approved.” Disclose every paid or gifted relationship, and make sure your influencers do too. When a claim is central to the brand and you are unsure which side of the line it sits on, that is the moment to pay a regulatory or advertising attorney for an hour of review, which is far cheaper than a warning letter or a lawsuit.

Frequently Asked Questions

Can I say my skincare is “anti-aging”?

Carefully. General “anti-aging” language framed around appearance, like “reduces the look of fine lines,” is usually acceptable as a cosmetic claim. But claims that the product changes the skin’s structure, “boosts collagen,” “stimulates cell renewal,” “erases wrinkles,” cross into drug territory and can trigger an FDA warning letter, because they describe an effect on the body rather than on appearance.

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

A cosmetic claim describes cleansing or beautifying, meaning how a product makes you look. A drug claim says the product treats or prevents a disease or affects the structure or function of the body. The distinction is in your wording, not your ingredients. A drug claim legally makes the product a drug, which requires FDA approval that cosmetics do not have.

Can I call my product “natural,” “clean,” or “chemical-free”?

“Natural” and “clean” have no legal definition, so you can use them, but you take on real risk if they mislead customers about what is actually in the product, which has fueled many class-action lawsuits. Avoid “chemical-free” entirely, because it is literally false and everything is made of chemicals. If you use “organic,” be aware it can pull you under USDA and state organic rules.

Do influencers have to disclose that I paid or gifted them?

Yes. Under the FTC’s endorsement guides, any material connection, payment, free product, affiliate commissions, or employment, has to be clearly and conspicuously disclosed by the person endorsing your product. The disclosure has to be obvious, not hidden in a string of hashtags, and the brand shares responsibility for making sure it happens.

Is my cosmetic FDA-approved?

No. The FDA does not approve cosmetics before they go on the market. Claiming that your cosmetic is “FDA-approved” is false and illegal. The FDA regulates cosmetics and can take action against unsafe or misbranded products, but that is not the same as approving them.
