How long does it take for GHK-Cu to improve skin healing?

GHK-Cu (Copper Peptide) typically shows visible improvements in wound healing within 2-4 weeks of consistent use. It works by stimulating collagen synthesis, promoting angiogenesis, and activating tissue remodeling pathways. Clinical studies have demonstrated enhanced healing rates for surgical wounds and chronic ulcers. <a href='https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4594048/' target='_blank'>Clinical evidence for GHK-Cu</a>
