What is AHK-CU?

Tripeptide (cupric peptide) is formed by three amino acids, tripeptide is also called blue cupric peptide; Glycine -L- histamine -L- lysine. Tripeptide a ternary molecule consisting of three amino acids linked by two peptides. It can effectively block the nerve conduction of a acetylcholine substance and has the effect of relaxing muscles and improving dynamic wrinkles.

They play their roles by effectively complexing and transporting copper blasts. For example, the complexed copper blasts stimulate the biosynthesis of collagen in fibroblasts, thereby promoting rapid wound healing.

Cuprin can also effectively block the nerve conduction of acetylcholine, which has the effect of relaxing muscles and improving dynamic wrinkles. Triseptide is now widely used as cosmetic additive.
