Also: Copper peptide GHK
✨Copper PeptideCopper delivery for collagen/elastin synthesis. Activates tissue remodeling, attracts immune cells to injury sites. Levels decline significantly with age.
Pickart (J. Cosmetic Dermatol.) reviews GHK-Cu's role in stimulating collagen, elastin, and glycosaminoglycan synthesis, improving skin density, thickness, and reducing fine lines.
moderatePickart et al. show GHK-Cu regulates expression of 4,000+ human genes, shifting patterns from diseased to healthy states applicable to COPD, cancer, and aging.
preclinicalComprehensive review demonstrating GHK-Cu accelerates wound closure, promotes angiogenesis, reduces scarring, and exhibits anti-inflammatory and antioxidant properties.
moderateStudy shows GHK-Cu increases collagen I and III gene expression, regulates metalloproteinases (MMP1, MMP2) and TIMP1, supporting balanced tissue remodeling.
preclinicalResearch demonstrates GHK-Cu provides UV photoprotection, reduces oxidative stress markers, and activates multiple regenerative and antioxidant genes in dermal cells.
preclinicalTopical or injectable; low risk. Long history of safe topical use in cosmetics.
