GHK-Cu is a naturally occurring tripeptide-copper complex that functions as a potent modulator of tissue remodeling and cellular regeneration, by specifically upregulating collagen and elastin synthesis through the activation of dermal fibroblasts. It also accelerates wound healing and promotes vascular endothelial growth factor (VEGF) for improved microcirculation. Its ability to quench free radicals and provide DNA-protective antioxidant activity makes GHK-Cu a foundational tool in clinical protocols aimed at systemic anti-aging and biological repair.
