In a landmark study published in the Journal of Investigative Dermatology , researchers found that GHK-Cu was more effective than vitamin C and retinoic acid in stimulating collagen production in aged human skin

The biological evidence is robust at the cellular level, and clinical results are promising but limited by small study sizes, industry sponsorship, and absence of independent replication

Researchers examine GHK-Cu in models involving collagen-associated signaling, skin-cell biology, angiogenesis, wound-response pathways, antioxidant response, and tissue-remodeling behavior
