Research indicates that GHK-Cu may be partially protected from digestion due to its small size and copper binding, which could improve stability
The GHK-Cu complex adopts a square-planar geometry, coordinated through the nitrogen atoms of the imidazole ring of histidine, the -amino group of glycine, and the deprotonated amide nitrogen of the glycine-histidine peptide bond
Best for : Patients looking for proven renewal, texture improvement, and acne or pigmentation support, especially those who want a more tolerable retinoid experience
