If you're building your first skincare line, you've probably already written a product description that promises glowing, flawless, "clinically proven" results — then wondered if you're allowed to say any of that. You're not alone. What claims skincare products can make is one of the most confusing parts of launching a brand, because the rules differ by country, by ingredient, and by how strong the wording is. This guide won't give you legal advice (you still need a professional review for your specific market), but it will help you understand the categories of claims, the common traps first-time founders fall into, and how to talk to your supplier so your packaging doesn't need a redo before you even launch.
Why skincare claims are regulated at all
In most markets, skincare sits in a gray zone between cosmetics and drugs. A cosmetic is generally allowed to clean, beautify, or change appearance. The moment a claim suggests you're treating, curing, or altering the structure or function of the body — think "cures acne" or "eliminates wrinkles permanently" — regulators in many countries will treat that as a drug claim, which triggers a completely different (and much heavier) approval process. This is exactly why the wording on your label matters as much as the formula inside the bottle. First-time founders often assume a bold claim makes the product more attractive, but if a customs officer or regulator in your target market flags it, you could face returned shipments or forced relabeling. Always check with the regulatory body or customs authority in your destination country before finalizing claim language — rules genuinely vary and change.
Cosmetic claims vs. drug claims vs. structure/function claims
It helps to think of claims in three rough buckets. Cosmetic claims describe appearance and sensory effect: "hydrates skin," "reduces the appearance of fine lines," "brightens dull-looking skin." These are generally the safest zone for skincare. Drug claims imply treatment of a medical condition: "treats eczema," "cures acne," "heals psoriasis" — these usually require drug registration, which is a different (and slower, costlier) path than most small brands take. Structure/function claims sit in between and are trickier: "boosts collagen production" or "reduces inflammation" can be acceptable in some markets with the right substantiation, but risky in others without it. If you're working with a factory on a custom formula, ask them directly what claim language they've successfully used for similar products before — they've usually seen what gets through and what gets flagged.
The substantiation problem: can you actually back up what you say?
Even claims that are legally allowed need to be backed by something — ingredient data, a stability test, a small consumer trial, or published research on the active ingredient. This is called substantiation, and it's often the gap between what a brand wants to say and what it can defensibly say. A founder might want "clinically proven to reduce wrinkles in 7 days," but unless there's an actual clinical study behind that exact formula, that line is a liability, not a selling point. A more honest, still compelling alternative: "formulated with [ingredient] shown in studies to support skin elasticity." This distinction — your product having a studied ingredient vs. your finished product being clinically tested — is one of the most common sources of confusion for new brands, and it's worth clarifying with your manufacturer before you write a word of copy.
Where beauty supplements fit into the claims conversation
If your brand includes beauty supplements alongside topical skincare, the claims landscape shifts again — supplements are typically regulated as food or health products in most countries, not cosmetics, and the rules around what you can say about skin, hair, or nail benefits are often stricter, not looser. Phrases like "supports healthy skin" tend to be more defensible than "reverses aging from within." If you're building a brand that spans both categories, it's worth treating each product type's claims separately rather than copy-pasting language across your whole catalog, since a line that's fine on a serum label might not be fine on a supplement bottle.
Working with your supplier on claims from day one
The earlier you talk about claims, the fewer surprises later. When you brief a factory on a custom formula, ask what the key active ingredients are, at what concentration, and whether there's existing documentation (ingredient studies, stability data, or test reports) you can reference — not quote directly, but use as a basis for honest wording. This is also where working with experienced Thai beauty suppliers can genuinely help, since many have exported to multiple regions and have seen which claim styles tend to cause friction at customs or with retail platforms. Don't assume your supplier will write your marketing copy for you, but do assume they can tell you whether a claim matches what the formula is realistically capable of.
A practical checklist before you finalize packaging copy
Before your artwork goes to print, run through a short list: Does the claim describe appearance rather than medical treatment? Can you point to any data or ingredient research behind it? Have you checked wording against your target market's cosmetic labeling guidelines (not just your home country's)? Have you avoided absolute words like "cures," "eliminates," or "permanently"? And have you considered how the same claim reads on a supplement vs. a topical product, if your line includes both? This kind of careful, unglamorous checking is a core part of brand building — it won't show up in your Instagram photos, but it's what keeps your brand sellable in more than one market over time. Platforms like 5FINE that work across formulation and sourcing can be a useful reference point when you're comparing how different suppliers handle claims, alongside other Thai beauty suppliers and manufacturers you're evaluating.

FAQ
Frequently asked questions
Can I say my skincare product is 'clinically proven'?
Only if there's an actual clinical study behind that specific finished formula — not just the individual ingredient. If the study is on the ingredient alone, it's more honest (and usually safer) to say the ingredient has been studied, rather than claiming the finished product is clinically proven.
Is 'anti-aging' an allowed claim?
In many markets it's commonly used and treated as a cosmetic claim, but the specifics you pair with it matter. "Reduces the appearance of fine lines" is generally safer than "reverses aging" or "regenerates skin cells," which can tip into drug or structure/function territory depending on the country.
Do beauty supplements follow the same claim rules as topical skincare?
No, they're usually regulated differently since supplements are often classified as food or health products rather than cosmetics. Claims about skin, hair, or nail benefits for supplements are often reviewed more strictly, so it's worth checking rules separately rather than reusing skincare label language.
Who should I ask to review my final claim wording?
Ideally a regulatory or labeling consultant familiar with your specific target market, since rules differ by country and change over time. Your supplier can often flag obvious issues based on past export experience, but that's a starting point, not a substitute for a market-specific legal check.
