GHK-Cu is studied in preclinical research on extracellular matrix remodeling, fibroblast and keratinocyte signaling, hair follicle research, dermal wound model studies, and copper-dependent enzyme research
Clinical studies utilizing facial application of 2-3% GHK-Cu serums over 12-week periods have documented measurable improvements across multiple photoaging parameters, including 20-35% reductions in fine line depth, 15-25% improvements in skin elasticity measurements, and 25-40% increases in dermal density as assessed through high-frequency ultrasound imaging
