The molecule
GHK is glycine, histidine, and lysine. When the tripeptide binds Cu²⁺, it forms GHK-Cu. Published cell, tissue, animal, and topical research reviews describe findings across collagen and extracellular-matrix activity, inflammatory signaling, antioxidant pathways, angiogenesis, and tissue repair.
Human topical research
Participants had mild to advanced signs of photoaging.
The study followed facial application of a GHK-Cu cream.
The review reports changes in density, thickness, laxity, fine lines, and wrinkle depth.
