When Your Balm Becomes a Drug: EU Borderline Products

A lip balm sits comfortably in cosmetic territory until someone writes "heals cracked, bleeding lips" on the packaging. Change the words to "soothes and softens dry lips" and it's still a cosmetic. Change them to "heals" with a therapeutic implication, and you've potentially stepped over a line that has nothing to do with the formula and everything to do with the claim.

This borderline zone trips up experienced formulators as often as new ones, because the ingredients often don't change at all. The classification shift happens in the marketing copy.

What makes something a cosmetic under EU rules

Regulation (EC) No 1223/2009 governs cosmetics in the EU, and it defines cosmetic products largely by function: substances applied to external parts of the body (or teeth and mucous membranes) with a view to cleaning, perfuming, changing appearance, protecting, keeping in good condition, or correcting body odor. Notification happens through the CPNP portal, you need a Responsible Person established in the EU, and you keep a Product Information File along with a Cosmetic Product Safety Report signed by a qualified safety assessor.

That's the cosmetic lane. The moment your product's intended function shifts toward treating or preventing disease, restoring or modifying physiological functions through a pharmacological, immunological, or metabolic action, you're potentially looking at a medicinal product instead, which falls under an entirely different regulatory framework with pre-market authorization requirements that are far more involved than a cosmetic notification.

Where the line actually gets crossed

It's rarely the ingredient list alone. It's usually one of these:

• The claim implies treatment of a medical condition. "Reduces the appearance of fine lines" is cosmetic language. "Treats eczema" or "clears acne" implies a therapeutic effect on a diagnosed condition, which points toward medicinal territory.
• The claim implies a physiological change beyond the surface. Cosmetics are meant to act on the outer layers of skin. Claims implying the product changes how skin functions at a deeper physiological level start to resemble drug claims.
• The product targets a named disease or its symptoms specifically. "Soothes irritated skin" is generally fine. "Treats dermatitis" names a medical condition and assigns a treatment function to it.
• Antimicrobial claims stray into biocidal territory. A hand cream that claims to moisturize is a cosmetic. The same cream claiming to "kill 99.9% of bacteria" is making a claim that may fall under biocidal product regulation instead, which again is a different framework with its own approval process.

Common borderline categories worth extra care

A few product types sit right on this line often enough that it's worth double-checking claims every single time, not just assuming last year's approved wording still works:

• Lip and hand balms marketed for "cracked" or "damaged" skin
• Anti-acne washes and spot treatments
• Products claiming to address dandruff, which typically fall under drug regulation rather than cosmetic regulation in most frameworks
• Sunscreens, which in some markets are treated as cosmetics but in others (the US, notably) are regulated as an OTC drug rather than a cosmetic
• Antiperspirants, generally treated as drugs rather than cosmetics
• Toothpaste with fluoride, typically regulated as a drug product due to the fluoride's therapeutic function

A practical way to self-check your claims

Before finalizing packaging copy, run each claim through a simple filter:

1. Does it describe appearance, cleansing, or maintenance (moisturizes, cleanses, softens, protects, perfumes)? That's solidly cosmetic language.
2. Does it name a medical condition (eczema, dermatitis, acne as a diagnosis rather than a cosmetic concern, fungal infection)? That's a warning sign.
3. Does it promise a cure, treatment, or prevention of disease? That's medicinal language, full stop.
4. Does it claim to kill or eliminate microorganisms as the primary function? That may be biocidal rather than cosmetic.

If a claim raises a flag on points two through four, it's worth getting a second opinion, ideally from someone with regulatory affairs experience in your specific market, before that wording goes anywhere near packaging or a website.

Why this matters more than it seems

Getting reclassified after the fact isn't a paperwork inconvenience. It can mean a product needs to be pulled, reworded, or in some cases go through an entirely different approval pathway before it can be sold again. The safety assessor signing your CPSR is also relying on the product being correctly classified as a cosmetic in the first place. A safety assessment built for a cosmetic doesn't cover the bases a medicinal product authorization would require.

Ingredient screening and claim classification are two separate jobs, and it's worth treating them that way. Cosmetic Comply focuses on the ingredient side, matching your formula to INCI names and CAS numbers and screening against prohibited and restricted lists, which is the groundwork every filing needs regardless of classification. But no ingredient tool can approve your marketing copy. That review belongs with a qualified person familiar with borderline product rules in your specific target market, and it's worth getting that check done before the claim, not the formula, becomes the problem.
