GHK-Cu

GHK-Cu is reported to repair skin barrier proteins, improve skin elasticity and firmness, reduce hyperpigmentation, stimulate collagen, decrease local inflammation, and may modestly support hair growth. GHK-Cu is a tripeptide made of glycine, histidine, and lysine complexed with copper. GHK-Cu levels measurably decline with age. GHK-Cu stimulates collagen production, accelerates wound healing and contraction, and reduces inflammation. GHK-Cu is primarily administered topically as a facial product for skin rejuvenation or as a specialized scalp foam for hair loss. GHK-Cu is naturally present in human plasma and has been isolated from saliva and urine.
