Copper acetate peptide, also known as blue copper peptide. Copper peptide, also known as tripeptide in Chinese; Glycyl-L-histomyl-L-lysine. Peptide is a small molecule protein composed of amino acids, which are more easily absorbed by the skin and have more significant effects. It was first isolated from human plasma in 1973 and was discovered to have wound repair function in 1985. In 1999, researchers believed that copper peptide and its copper repair products can serve as activators of tissue remodeling, and it is also a signaling peptide, Promote the degradation of a large amount of collagen aggregates outside scars, the synthesis of normal collagen in the skin, the generation of elastin, proteoglycans, and glucosamine glycans, the growth rate and migration of different cell types, anti-inflammatory, and antioxidant responses.
