Copper Tripeptide-1

Copper tripeptide-1 (GHK-Cu) is the canonical copper peptide: a tripeptide that chelates copper(II) ions and delivers them to skin cells, where the complex upregulates collagen, elastin, and proteoglycan production while breaking down excessive, damaged scar tissue — a remodelling effect unique among peptides. Clinical use documents improved elasticity, thickness, and wound repair. At 0.05–0.5% it suits aging, thinning, or post-peel skin. Because copper can be displaced by strong acids and direct antioxidants, use it in a separate routine step from pure vitamin C. A cornerstone of evidence-based peptide therapy with genuine regenerative credentials.
