The gel applied at the end of a microneedling appointment is doing more regulatory work than anyone in the room realises. Growth-factor topicals — PDGF, EGF, and branded blends — have moved onto med spa menus fast, usually described in exactly the words that classify them as drugs.
1. The claims. "Accelerates healing," "speeds recovery," "regenerates," "repairs tissue" describe what the product does to the body. Those are drug claims. So is "boosts collagen production" — that's a structure/function claim, and it's a drug claim even when the product is sold as a cosmetic.
2. The route. Applying the product onto deliberately disrupted skin — post- microneedling, post-laser, post-RF — is administration into living tissue rather than surface cosmetic use. That places it outside the cosmetic lane regardless of how the claims are worded. You cannot copy-edit your way out of this one.
With exosomes, the argument is that no approved product exists. With PDGF, one does.
Recombinant human PDGF is the active ingredient of an FDA-approved prescription drug, approved for lower-extremity diabetic neuropathic ulcers. So a spa gel promising recovery isn't claiming an effect nobody has ever approved — it is claiming the effect of an approved prescription drug, without being that drug, for a use that is not that indication.
That is a worse position, not a better one. And "off-label" isn't available here: the compounded gel on your shelf is not the approved product, so there is no approval to be "off" of.
| Safe | Crosses over |
|---|---|
| "Improves the appearance of texture and fine lines" | "Accelerates skin recovery" / "speeds healing" |
| "For smoother-looking, more refreshed-looking skin" | "Boosts collagen production" / "stimulates collagen" |
| Sold as a take-home cosmetic for intact skin | Applied in-clinic immediately after microneedling, laser or RF |
| Naming the source of the growth factors | "Lab-engineered," "regenerative," "bio-active" as the selling point |
"A topical serum formulated with growth factors, intended to improve the appearance of firmness, texture and fine lines. Individual results vary."
Every claim about appearance. Nothing about what the product does to tissue. Identify the source of the growth factors, and confirm your cosmetic listing obligations.
If it's applied in-clinic onto treated skin, the wording isn't the issue — the delivery route is, and that goes to counsel.
Check your aftercare handouts and consent forms, not just the website. They are marketing too, and they are the version a regulator asks for. A service page that has been carefully cleaned up doesn't help much when the printed aftercare sheet still says the gel "speeds healing."
