GHK-Cu

How it works

GHK, three amino acids found in blood, clasping a copper atom; in serums, meant to spur fibroblasts, the skin's collagen makers.

What it's made of

3 amino acids (glycine, histidine, lysine) bound to a copper atom. GHK is in human blood; Loren Pickart isolated it in 1973. Nothing in it is changed: the copper is just added.

What it's for

Prescribed for

Nothing: it is a cosmetic.

Sold as

The copper peptide that “regenerates” the skin: more collagen, more firmness and better recovery after a laser.
