There is a sentence that appears on a great many skincare pages, in a great many fonts, and it goes something like: clinically proven to reverse the signs of ageing. Almost every word in it is doing something questionable, and the last four are doing something specific — they are making a claim that, taken literally, would move the product into an entirely different regulatory category.
the actual distinction
A cosmetic is a product intended to cleanse, beautify or alter appearance. A drug is intended to diagnose, treat, mitigate or prevent disease, or to affect the structure or function of the body. The dividing line is not the formula. It is the claim made about it. The identical bottle becomes a drug the moment you say it treats something.
This is why the language in the category is so strange, and why so much of it reads as evasive. Writers are steering around a legal line while trying to sound confident. The results are the verbal contortions everyone recognises — the look of, the appearance of, helps to support.
The identical bottle becomes a drug the moment you say it treats something. The line is drawn by the sentence, not the formula.
we could write around it, and do not
The evasions work. You can imply a great deal without ever writing an actionable sentence, and plenty of brands make a good living in that gap. We have decided the gap is the problem rather than the solution, for a reason that is commercial as much as ethical: our reader has been marketed at for thirty years and can hear the hedge.
So the rules here are narrower than the law requires.
- Nothing treats, cures, heals, repairs or regrows. Not hedged — not written.
- No before-and-afters, no percentages from a study of nineteen people, no "clinically proven" attached to a claim the clinic never tested.
- Ingredients are named at the concentration or the position we can actually verify, or not quantified at all.
- If a formula contains something a reader might avoid — beeswax, fragrance, a nut-derived oil — it is on the page, not buried in the INCI.
- Pro-this-age. Never anti-ageing, never "correcting", never the language of a problem to be solved.
what is left to say
Quite a lot, as it turns out. That skin holds less water than it did, and here is what holds water. That a lighter oil absorbs where a heavy one sits. That the neck gets left out of the routine and does not need to be. None of that requires a claim we cannot stand behind.
The smaller promise has a useful property: it is the one you can check.
