28.2% in controls) Improved collagen organization and increased deposition Enhanced glutathione levels and antioxidant enzyme activity Increased angiogenesis through VEGF and FGF-2 stimulation Reduced pro-inflammatory markers (TNF-, IL-6) with decreased NF-B signaling Fibroblast migration stimulation and extracellular matrix remodeling GHK-Cu research consistently demonstrates that the peptide is biologically active at very low concentrations in the nanomolar range (110 nM)

Researchers working with sensitive skin models should begin with once-daily application and monitor for local reactions before increasing frequency
