GHK-Cu

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

When applied topically, copper peptides work as an antioxidant, promote collagen and elastin production, and soften the appearance of fine lines and wrinkles." Copper is also an anti-inflammatory that speeds up wound healing, meaning it's great for treating scarring, pigmentation, and redness caused by inflammation
