Emerging research suggests topical copper peptide formulations may support the healing environment in certain slow-healing or chronically inflamed wounds by helping promote: Collagen synthesis Tissue granulation Improved skin repair signaling Reduced oxidative stress Better tissue remodeling Supportive wound-healing microenvironment Some regenerative practitioners are exploring topical GHK-Cu in carefully selected cases involving: Delayed skin healing Cosmetic procedure recovery Aging-related slow healing Fragile skin Superficial tissue recovery support However, it is extremely important to understand: GHK-Cu is not a replacement for proper wound care
