Gopal Grandhige, MD, FACS, Board-Certified Surgeon Last Reviewed: February 28, 2026 GHK-Cu is a copper peptide complex (glycyl-histidyl-lysine combined with copper) that naturally occurs in human saliva, plasma, and urine
What Topical Does Well Published research documents topical GHK-Cu's effects in three primary areas: Wrinkle and fine-line reduction -- consistently documented across multiple facial and eye-area studies Collagen and extracellular matrix stimulation -- increased synthesis of collagen, elastin, glycosaminoglycans, and decorin in treated skin Post-procedure recovery -- accelerated healing documented in post-laser resurfacing protocols The limitation is equally clear: topical delivery confines the peptide's activity to the skin
