Cosmetic claims are the statements you make about what your product does: on the label, in ads, on the website, in social media, and in every piece of marketing that goes out.
They are also the fastest way to get a brand into regulatory trouble if you do not handle them properly.
Most claim problems come down to timing rather than ignorance of the rules. The rules get ignored until the packaging is already printed, the ads are already running, and fixing it costs several times more than planning would have.
I have seen brands spend 8,000 EUR/USD to reprint packaging to add "dermatologist tested" three weeks before launch, when handling it three months earlier would have cost 2,000 EUR/USD total. (Cost figures throughout this article are indicative estimates that vary by manufacturer, region, and project scope.)
After 30 years in the hair and beauty sector, most recently in private label cosmetics, I can tell you that claims are where first-time founders make more expensive mistakes than almost anywhere else.
This guide walks you through what you can legally say, what each claim costs to make, the most common mistakes I see, and a quick reference for safe versus risky language.
Cosmetic claims are regulated in every serious market. The two frameworks most brand founders deal with are the EU and the US. If you sell in both, you need to meet the stricter of the two for each claim.
The EU regulates cosmetic claims under Commission Regulation (EU) 655/2013, which sets six common criteria that every claim has to meet. These six criteria sit inside the broader framework covered in the EU cosmetics regulation guide.
Legal compliance. A product cannot claim a benefit that is mere compliance with minimum legal requirements.
The textbook case is a pack that announces it complies with EU cosmetics legislation: compliance is the baseline, not a benefit. "Not tested on animals" often gets filed here by mistake. Article 20(3) of Regulation (EC) No 1223/2009 expressly permits a reference to the fact that no animal tests have been carried out, but only if neither the manufacturer nor its suppliers carried out or commissioned any animal test on the finished product, on the prototype or on any ingredient in it, and used no ingredient that others tested on animals to develop new cosmetic products. That condition reaches back into the supply chain, which is what makes the claim hard to hold up, not illegal.
Truthfulness. If you say a product contains honey, the honey has to be deliberately present. That is criterion 2(1), and it sets no percentage. An effective concentration only enters the picture one step further on, under criterion 3(6), when you attribute the honey’s properties to the finished product.
If you say "paraben-free," no paraben can be present, and the parabens sit in entry 12 and entry 12a of Annex V to Regulation (EC) No 1223/2009. A formaldehyde releaser such as diazolidinyl urea, which is entry 46, belongs to a different family and does not make a paraben-free statement untrue.
Evidential support. Claims must be supported by adequate and verifiable evidence, at a level consistent with the type of claim.
The evidence lives in the Product Information File, which authorities can audit at any time. A "clinically proven" claim without a clinical study on file is a compliance problem waiting to happen.
Honesty. Claims cannot exceed what the product actually does.
"Reduces wrinkles in 7 days" needs evidence that supports exactly that, and if that evidence is a study, a methodology that is valid, reliable and reproducible. The Regulation sets no minimum panel size: how many subjects you test is a methodological choice you have to justify, and in practice labs and retailers expect around 30. Clear hyperbole like "the best cream in the world" needs no substantiation at all, but a superlative that presents performance beyond your evidence does.
Fairness. Claims cannot denigrate competitors or competitor ingredients unfairly.
You cannot imply that an entire category (all parabens, all silicones, all sulphates) is dangerous when the science does not support that.
Allowing informed decisions. The claim must give the consumer enough real information to make a choice.
Vague claims that imply benefits without anchoring them to something specific do not meet this criterion. "Improves skin quality" does not help a consumer decide. "Visibly reduces the appearance of dark spots within 4 weeks of twice-daily application" does.
The US takes a different approach. There is no EU-style single regulation for cosmetic claims. Instead, the FDA and FTC enforce a critical distinction.
A cosmetic is a product intended to cleanse, beautify, promote attractiveness, or alter appearance.
A drug is a product intended to affect the structure or function of the body, or to diagnose, cure, treat, or prevent disease.
The moment your claim crosses from cosmetic (appearance) into drug (structure or function), you have a drug product in the eyes of the FDA. Drugs require a completely different approval process, which is expensive and slow.
Claims that cross into drug territory:
Claims that stay on the cosmetic side:
The word "appearance" does a lot of work in cosmetic marketing. It keeps claims focused on visible, surface-level outcomes rather than physiological change.
MoCRA (the Modernization of Cosmetics Regulation Act) also requires substantiation for safety, even though US rules are less explicit about efficacy substantiation than EU rules. For the full picture of US compliance obligations beyond claims, see the FDA cosmetics regulations guide.
The FTC separately enforces truth-in-advertising. They treat cosmetic claims with the same standard as any other consumer product.
If your claim implies a change in the body’s structure or function, or cures or treats a disease, you have a drug claim, not a cosmetic claim. Rewrite it.
Most claims can be reframed in one word without losing marketing impact.
The word "appearance" is the brand founder’s best friend. Use it. "Reduces the appearance of wrinkles" is a cosmetic claim. "Reduces wrinkles" drifts toward drug territory.
If your claim is about appearance, feel, experience, or consumer perception, you have a cosmetic claim.
It still needs evidence. But it stays in the cosmetic lane.
Every claim you might put on a product label, ad, or website falls into one of three categories. Each category has a different cost structure and a different level of complexity.
Understanding which category your claims fall into is how you avoid the most common expensive mistake in product development: adding a claim after the packaging is printed.
These are claims tied directly to what is (or is not) in the formula.
"Vegan." "Cruelty-free" (where supplier declarations back it). "Silicone-free." "Sulphate-free." "Paraben-free." "SLS-free." "Fragrance-free." "Contains hyaluronic acid." "With 5 percent niacinamide."
If the formula meets the criteria, you can make the claim. The cost to support these claims is essentially the cost of the formula that delivers them. You are not required to run separate testing.
The practical workflow is simple. You list every formula-dependent claim you might want in your concept brief. The manufacturer comes back on the first formula analysis and tells you which are already satisfied by the proposed formula, and which would need reformulation.
If meeting a specific claim requires replacing an active ingredient that actually does the work, you have a trade-off to weigh.
Sometimes the claim is worth more than the ingredient. Sometimes it is not.
For context on how these decisions fit into concept development, see the cosmetic product concept guide.
These are claims that require a dedicated test, run by an independent lab or clinical panel, on the finished product.
"Dermatologist tested." "Clinically proven." "Suitable for sensitive skin." "Hypoallergenic." "Nickel free." "Tested under dermatological control." "Reduces the appearance of wrinkles by X percent." "Visible hydration for 24 hours."
Each of these requires a specific test with a specific protocol, run on a representative panel of subjects, with documented methodology and results.
Typical cost range: 1,500 to 5,000 euros per claim per product.
Some of these tests can be combined. A dermatological tolerance test that supports both "dermatologist tested" and "suitable for sensitive skin" is often one single study with dual output.
But the cost scales with the number of claims and the number of products.
This is where the most expensive mistake happens.
A founder decides they want "dermatologist tested" on the label after the packaging is already printed, after the website copy is already written, and after the first batch is in warehouse.
The cost of adding that claim at that point:
Total: 5,000 to 15,000 euros for a claim that could have been handled upfront for the cost of the test alone.
The most expensive sentence in cosmetic marketing is "I’ll add the claim later." Every time, without exception.
The fix is to list every claim you might want from the first call with the manufacturer. Even the ones you are not sure about.
Better to plan for a test you decide not to run than to discover at the end that you need one.
These are claims that require both formula compliance and an audit or certification from an external organization.
"Vegan certified" (by The Vegan Society, V-Label, or similar). "Cruelty-free certified" (Leaping Bunny, PETA). "COSMOS Organic." "Ecocert." "USDA Organic." "Fair Trade certified."
Each certification has its own standards body, its own application process, its own audit schedule, and its own annual fees.
Typical cost range: 500 to 3,000 euros per year per certification, plus one-time application fees.
For multiple products or multi-market compliance, these costs scale.
Certification claims are worth the cost when the claim is central to the brand positioning and the customer specifically looks for it.
A natural brand targeting customers who actively search for COSMOS-certified products probably needs the certification to be credible.
A mainstream brand that wants to mention "cruelty-free" in marketing copy may not need Leaping Bunny certification if the factual claim is true and defensible.
Certification is an investment you make when the badge of trust matters to your audience, not an automatic upgrade on the uncertified version of the same claim.
Across the brand launches I have guided, I see the same five mistakes over and over. Every one of them is preventable, usually with a 30-minute conversation at the right moment in product development.
Here they are, in order of how often they hurt brands.
This is the single most expensive mistake in cosmetic marketing, and I already touched on it in the section on third-party testing.
The founder either forgets to include the claim in the initial brief, or does not realize the claim requires testing until the marketing copy is being drafted.
By that point, the formula is locked, the packaging is ordered, and the fix costs several times what it would have cost upfront.
Fix: list every possible claim during the concept phase. Let the manufacturer tell you which require testing, which need certification, and which the formula supports naturally.
Decide then, not later.
A founder writes copy that says the product "stimulates collagen," "heals acne," "treats hyperpigmentation," or "regrows hair."
These read well. They sound authoritative.
They also potentially reclassify the product as a drug under FDA rules, which triggers a completely different and far more expensive regulatory framework.
Even in the EU, where the cosmetic-drug line is drawn differently, claims that imply disease treatment or physiological change are prohibited.
Fix: run every claim through the "appearance test." Does it talk about how the product changes how the skin or hair looks or feels? Cosmetic claim. Does it talk about what the product does inside the body? Drug claim. Rewrite.
"Paraben-free" is a claim that regulators increasingly view as problematic.
It implies parabens are dangerous, when in fact they are legally permitted preservatives with decades of safety data.
The EU specifically guides against "free from" claims when they denigrate legally permitted ingredients, under the fairness criterion of Regulation 655/2013.
"Free from" claims also trip on the truthfulness criterion when a precursor ingredient releases the substance you claim to be free from.
"Formaldehyde-free" when your formula contains diazolidinyl urea is a false claim, because diazolidinyl urea releases formaldehyde.
Fix: use "free from" claims sparingly and only when the claim is both legally defensible and truly accurate, including precursors.
When in doubt, make the positive claim (what the product contains) instead of the negative claim (what it does not).
"Visibly reduces wrinkles in 7 days." "Eliminates dark spots in 2 weeks." "Makes hair 50 percent stronger."
These claims sound great in ads. They also create a problem in three directions at once.
Regulatorily, each specific claim needs specific evidence. A claim of "wrinkle reduction in 7 days" needs evidence that showed exactly that, with a methodology that holds up to scrutiny.
Commercially, the claim sets an expectation the product has to meet.
Customers who do not see results in the promised timeframe leave negative reviews, request refunds, and damage brand reputation.
Legally, the FTC and EU member state authorities can act against unsubstantiated claims, with real consequences for the brand.
Fix: undersell on timing and specifics.
"Visible improvement in skin appearance with consistent use over 4 to 6 weeks" is honest, defensible, and sets realistic expectations.
The sales impact of the slightly softer claim is almost always smaller than the damage of over-promising.
A common founder shortcut: look at what competitor brands say on their labels, write similar claims for your own product, and move on.
The problem is that the competitor may have done testing that you have not.
Or the competitor may be making claims that are borderline and not yet enforced.
They might also just be breaking the rules and not yet caught.
Claims are not like brand names or packaging aesthetics, where you can take inspiration from others. Claims need their own evidence, for your specific product, in your Product Information File.
Fix: build your claims from your own evidence. What does your formula do? What can your manufacturer substantiate? What tests are you willing to pay for? Build the claim list from those answers, not from what competitors are doing.
The table below shows common reformulations from risky to safe language. Use it as a starting checklist when drafting marketing copy.
| Risky claim | Safer alternative | Why |
|---|---|---|
| "Removes wrinkles" | "Reduces the appearance of fine lines and wrinkles" | "Appearance" keeps it on the cosmetic side |
| "Cures acne" | "Helps improve the look of blemish-prone skin" | Treatment language implies drug claim |
| "Stimulates collagen" | "Supports skin firmness and elasticity appearance" | Structure/function is drug territory |
| "Regrows hair" | "Supports the appearance of fuller, denser-looking hair" | Regrowth is a drug claim |
| "Guaranteed results in 7 days" | "Visible results with consistent use over 4 to 6 weeks" | Specific timing needs matching evidence |
| "Paraben-free" (unqualified) | "Preserved with [alternative system]" | Naming what is in the formula clears the fairness criterion; "without parabens" carries the same denigration |
| "Not tested on animals" (unverified supply chain) | The same statement once supplier declarations cover every ingredient, or "cruelty-free" with certification | Article 20(3) permits it only if neither the manufacturer nor its suppliers tested or commissioned tests |
| "Heals" or "cures" anything | "Helps the skin look or feel..." | Treatment language reclassifies product |
| "Natural" (unqualified) | "Made with X percent natural-origin ingredients" | Unqualified "natural" is hard to defend |
For how these choices connect to the broader compliance picture, see the regulatory compliance overview. For specific formulation philosophies that affect which claims you can naturally support, see the formulation types guide. And once your claims are safe and substantiated, the next step is turning them into copy that actually sells, covered in the marketing strategy guide.
Claims are not a legal checkbox you deal with at the end of product development.
The brief you write before any formula work already commits you to most of them.
They are a strategic decision you make at the start, because they shape the formula, the testing budget, the packaging, the marketing copy, and the regulatory paperwork.
The brands that handle claims well do three things consistently.
They list every possible claim during the concept phase, before any formula work starts. The claim budget goes into the plan next to the formula budget, not as an afterthought. And "appearance" becomes the default word, the one that keeps the marketing powerful and compliant at the same time.
Handled that way, claims stop being a risk you carry into launch.
They turn into one of the sharpest tools you have for making the product sell.
What is the difference between a cosmetic claim and a drug claim?
A cosmetic claim describes how the product affects appearance, feel, or consumer experience ("reduces the appearance of wrinkles," "makes hair feel softer"). A drug claim describes how the product affects the body’s structure, function, or health ("stimulates collagen production," "treats acne," "regrows hair"). The same product can become a drug in the regulator’s eyes depending purely on the claims made. The word "appearance" is the practical line: if your claim is about appearance, it stays cosmetic. If it goes deeper, it enters drug territory.
How much does it cost to substantiate a cosmetic claim?
It depends on the type. Claims the formula supports directly (vegan, silicone-free, contains X) cost nothing extra beyond the formula itself. Claims requiring third-party testing (dermatologist tested, hypoallergenic, suitable for sensitive skin) cost 1,500 to 5,000 euros per claim per product. Claims requiring external certification (COSMOS, Leaping Bunny, Ecocert) cost 500 to 3,000 euros per year per certification plus application fees.
Can I say my product is "not tested on animals"?
Yes, but only on the condition Article 20(3) of Regulation (EC) No 1223/2009 attaches to it: neither the manufacturer nor its suppliers may have carried out or commissioned any animal test on the finished product, on the prototype or on any ingredient in it, and no ingredient may have been tested on animals by others to develop new cosmetic products. That is a supply chain question, and it is what makes the statement hard to hold up. The EU testing bans in Article 18 are a separate rule with their own timetable: 11 March 2009 for most of them, 11 March 2013 only for repeated dose toxicity, reproductive toxicity and toxicokinetics, so 2013 closed the regime rather than opening it. In markets where animal testing is not banned, the claim is allowed if truthful, but "cruelty-free" with a recognized certification is usually more credible.
What is the strongest evidence I can have for a cosmetic claim?
A published clinical study on the finished product, with a panel large enough for the result to hold up statistically, using validated methodology. Next best is an in-house or contracted clinical study on the finished product. Below that is ingredient-level evidence combined with a strong rationale for the finished product. The weakest acceptable evidence is supplier ingredient data alone, which is often not enough to support a specific product claim. Evidence lives in the Product Information File for EU markets.
Can I make claims based on what the ingredient does generally?
Partially. You can say "contains hyaluronic acid" and factually describe what hyaluronic acid does in general. You cannot automatically claim that your specific product delivers that result, because formulation, concentration, and delivery system all affect whether the ingredient works in the finished product. To claim the specific result, you need evidence on the finished product. For more detail on the ingredient-to-claim connection, see the cosmetic ingredients guide.
What happens if I make a claim I cannot support?
In the EU, member state authorities can order the claim removed, impose fines, and in serious cases require product withdrawal. The Product Information File must hold proof of the effect claimed where the nature or the effect of the product justifies it, and Article 11(3) requires it to be readily accessible to the competent authority, which can ask for it at any time. There is no scheduled audit of each file: the word audit does not appear in the Regulation, and what Article 22 asks of member states is market surveillance "on an adequate scale", plus a review of how that surveillance is working at least every four years. In the US, the FTC handles advertising claims and can bring enforcement actions, sometimes in class-action form. Beyond regulators, the bigger cost is often the marketplace: platforms like Amazon, retailers, and review sites remove products with unsupported claims, and once removed, relisting is difficult.
Do influencers and ambassadors need to follow the same claim rules?
Yes. If an influencer or brand ambassador makes a claim about your product, that claim counts as brand communication and falls under the same rules. You can be held responsible for what people say about your product on your behalf. Brief every influencer and ambassador on which claims they can make and which they cannot, and put it in your contract. "Softens my skin" is fine. "Cured my eczema" is not, regardless of who says it.
