GHK-Cu (Copper Peptide) is a naturally occurring peptide complex made of glycyl-L-histidyl-L-lysine bound to copper (Cu²⁺). It plays an important role in tissue repair, skin regeneration, and anti-aging processes. Key effects: ● Stimulates collagen and elastin production for firmer skin ● Promotes wound healing and reduces inflammation ● Supports hair growth and follicle health ● Acts as a powerful antioxidant and protects cells from damage GHK-Cu is found naturally in human plasma, saliva, and urine but declines with age. It’s commonly used in cosmetic creams, serums, and microneedling treatments for skin and hair rejuvenation
