Researched for: copper peptide and skin signaling
Also known as: Copper tripeptide-1, GHK copper
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is the most-studied regenerative copper peptide, first isolated from the albumin fraction of human plasma by Loren Pickart in 1973. It stimulates fibroblast production of type I collagen, elastin, and glycosaminoglycans/proteoglycans, with measurable increases in collagen synthesis at concentrations as low as 10nM within 48 hours in vitro. GHK-Cu accelerates every major phase of tissue repair (hemostasis, inflammation resolution, proliferation, remodeling) in both animal models and human studies, restores function of damaged fibroblasts, and reduces scarring. Microarray analysis by Pickart and others found GHK-Cu modulates over 4,000 human genes, with a majority trending toward a younger gene-expression profile - among the more extensively documented mechanisms in the cosmetic-peptide category.
