Product Description Tripeptide-1 copper is composed of tripeptide-1 and copper ions, also known as blue copper peptides, and its appearance is blue powder. Blue copper peptide was first discovered by American chemists in 1970. It exists in serum. In recent years, it has been widely used in the field of cosmetic peptides. It is also the main component of hair growth complex peptide. After penetrating into the skin, blue copper peptide can induce fibroblasts to form collagen by releasing signals. Copper ions attached to blue copper peptides can enter the cell and release after encountering enzymes. Copper ions themselves are important components for many enzymatic reactions. Proteoglycan is an important component of extracellular matrix, and copper blue peptide can promote the formation of skin to make skin full and elastic.
