Copper peptide GHK-Cu is a naturally occurring copper complex of a glycyl-L-histidyl-L-lysine peptide. Since it has three amino acids it is called tripeptide. The GHK-Cu tripeptide has strong affinity for copper(II) and was first isolated from human plasma. It can be found also in saliva and urine.

Function of Copper peptide

1.Tighten loose skin and increase elasticity

2.Improve skin clarity

3.Improve skin density and firmness

4.Reduce light damage and discoloration;

5.Reduce fine lines and deep wrinkles

6.The proliferation of keratinocytes is greatly increased

Copper peptide originally isolated from human plasma in 1973, and found that it has the function of wound repair in 1985, 1999, the researchers think that GHK copper and its compounds can be used as tissue remodeling of activator, it is also a signal peptide, promote scar outside a large number of the degradation of collagen protein concentration, normal skin synthesis of collagen and elastin, proteoglycan and grapes glycosaminoglycans generated, different cell types of the growth rate and migration, anti-inflammatory, oxidation reaction.
