GHK-Cu, a synthetic tri-peptide known as gly-cyl-L-histidyl-L-lysine, is renowned for its powerful anti-aging and skin rejuvenation properties. Discovered in the 1980s, GHK-Cu has demonstrated significant potential in skin remodeling, wound healing, and as an anti-inflammatory agent. It promotes the production of collagen, essential for maintaining skin firmness and elasticity, which helps reduce the appearance of fine lines and wrinkles. Research indicates that topical application can boost collagen levels by up to 70% and decrease wrinkles by 27%. Additionally, GHK-Cu enhances hair growth, with studies showing an 80% increase in antigen hair follicles, doubling follicle size over three months of treatment. This peptide not only tightens skin and improves its elasticity but also repairs skin barrier proteins and aids in wound recovery, making it a valuable component in both cosmetic and therapeutic dermatology.
