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. It also can be released from tissues in case of an injury. Since its discovery in 1973, GHK-Cu established itself as a powerful protective and regenerative ingredient, which is currently widely used in skin and hair products[1].
The benefits of Ghk-Cu include:
Tighten loose skin and reverse thinning of aged skin;
Repair protective skin barrier proteins;
Improve skin firmness, elasticity, and clarity;
Reduce fine lines, depth of wrinkles, and improve structure of aged skin;
Smooth rough skin;
Reduce photodamage, mottled hyperpigmentation, skin spots and lesions;
Improve overall skin appearance;
Stimulate wound healing;
Protect skin cells from UV radiation;
Reduce inflammation and free radical damage;
Increase hair growth and thickness, enlarge hair follicle size[1].
