GHK-Cu
well-studiedA naturally occurring copper-binding tripeptide with powerful skin regeneration, wound healing, and anti-aging properties.
Overview
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) with a high affinity for copper ions. It is found naturally in human plasma, saliva, and urine, with concentrations declining significantly with age. This decline correlates with visible aging effects.
Research shows GHK-Cu stimulates collagen synthesis, promotes wound healing, has anti-inflammatory effects, and may even influence gene expression patterns — switching aging-related gene activity toward a healthier, younger profile. It is used both topically (skincare) and via injection (systemic anti-aging).
