Copper Peptide (GHK-Cu)
INCI: copper peptide
GHK-Cu is a copper-binding tripeptide and one of the most researched peptides in skin science. It signals fibroblasts to produce collagen and elastin, stimulates glycosaminoglycan synthesis, and accelerates wound healing — it was originally discovered in human plasma for exactly that regenerative capacity. Studies show improved firmness, reduced fine lines, and faster post-procedure recovery at 0.05–0.5%. GHK-Cu also has anti-inflammatory and antioxidant activity. Caveat: avoid layering in the same routine with strong acids or direct vitamin C, which can decomplex the copper. Best paired with hydration and barrier lipids in a night regimen for cumulative renewal.
