Blue copper peptide is a small molecule protein and is the earliest discovered peptide. To put it more bluntly, this thing is a combination of a polypeptide (tripeptide-1) and a copper ion.

Copper peptide, also called Blue copper peptide,copper peptide, tripeptide-1 copper, abbreviated as GHK-Cu in English, has a rare structural sequence glycyl-L-histidyl-L-lysine-Cu (II).

Copper peptides can work under the epidermis or the outer layer of the skin. This is why peptides can help produce elastin in collagen deep in skin tissues.

Blue copper peptide is also called blue copper peptide and copper peptide. It is a complex of metal copper ion and tripeptide. Because it is rich in copper ions, the appearance presents a unique and elegant blue color, so it is called blue copper peptide.
