GHK-Cu

Also known as: Copper tripeptide, GHK-copper

Status

Cosmetic ingredient. A cosmetic ingredient used in skincare; in the US, cosmetics need no FDA approval before sale but must be safe, properly labelled and free of drug claims. It is not an FDA-approved drug, and injectable versions are not the same product as the serum in a bottle.

What it is

A three-amino-acid peptide that binds copper, naturally present in human plasma and declining with age. In skin it is studied for collagen, wound healing and follicle biology — which is why it appears in both skincare and hair-loss conversations.

What published research measured

Human data is mostly topical: small trials and mechanistic work. The injectable research-chemical market operates entirely outside that literature.
