Blue Copper Peptide Acetate(CAS300801-03-0), also known as GHK-Cu, is a stable complex formed by the tripeptide of glycine-histidine-lysine and copper ions (CAS No. 130120-57-9), presenting as a blue powder with good water solubility and a molecular weight of approximately 463.98. As a highly active beauty peptide, its core advantage lies in its multi-dimensional skin care effects: it promotes fibroblast proliferation and collagen synthesis by activating the MAPK signaling pathway, enhancing skin firmness by 17%-18% within 8 weeks, effectively reducing wrinkles and fine lines; it regulates the antioxidant enzyme system, with an antioxidant capacity 1.5 times that of vitamin C, and simultaneously inhibits inflammatory factors such as TNF-α, improving erythema by 43%, making it suitable for sensitive skin and post-medical aesthetic procedures; it also promotes ceramide synthesis, reducing transepidermal water loss by 22%-29%, and strengthening the skin barrier.
