Exosome therapy vs GHK-Cu
Two regenerative pitches for skin and hair: a copper peptide with real biology in a dish, and a clinic procedure the FDA has issued safety reports about.
Exosome therapy
Extracellular vesicles, EV therapy
No FDA-approved exosome product exists for any indication, and the agency reports blindness, tumor formation and infections from unapproved ones. Legitimate first-in-human work is under way; none of it supports what clinics sell.

Copper tripeptide
Real tissue-remodeling biology, mostly in-vitro and topical; a cosmetic signal, not systemic anti-aging proof.

Our verdict
Neither supports the rejuvenation claims made for it, but the risk is not symmetrical. GHK-Cu has genuine tissue-remodeling biology that is mostly in-vitro and topical — a cosmetic signal, not systemic anti-aging proof. Exosome therapy has no FDA-approved product for any indication, and the agency has reported blindness, tumor formation and infections tied to unapproved ones; legitimate first-in-human work is under way, and none of it supports what clinics currently sell. A topical with thin evidence and an injected procedure with safety reports behind it are not the same kind of bet.
Exosome therapy fits if
You are tracking the legitimate first-in-human extracellular-vesicle research rather than buying a clinic procedure today.
GHK-Cu fits if
You want the topical, cosmetic end of this claim and read the evidence as a skin signal rather than anti-aging.
