Journal of Aging Research · Vol. 2015 · pp. 648108 · 2015
Comprehensive review of GHK-Cu's mechanisms in skin remodeling and anti-aging. The copper peptide modulates over 4,000 human genes, stimulates collagen and elastin synthesis, promotes wound healing, and demonstrates antioxidant and anti-inflammatory properties. Clinical studies show measurable improvements in skin thickness, fine lines, and elasticity.
Key Findings
GHK-Cu modulates expression of over 4,000 genes involved in tissue repair and inflammation
Increases skin thickness by up to 120% in clinical studies
Reduces fine lines and wrinkles by 20–35% in controlled trials
Stimulates collagen, elastin, and glycosaminoglycan synthesis
Promotes wound healing and reduces scar formation
Methodology
Systematic review combining gene expression analysis (Broad Institute data), in vitro collagen synthesis assays, and clinical trials with validated skin measurement tools.
Limitations
Some clinical studies have small sample sizes. Long-term safety data for injectable GHK-Cu limited.
