Key scientific mechanisms: GHK-Cu stimulates fibroblasts to increase production of collagen, elastin, and hyaluronic acid crucial for skin firmness, elasticity, and tissue repair

Documented effects include: Upregulation of SOD1 (cytosolic Cu/Zn-SOD), CAT (catalase), and GPX1 (glutathione peroxidase 1) mRNA and protein in multiple cell types NRF2 nuclear translocation and ARE-driven gene induction (HO-1, NQO1, GCLC, TXNRD1) Reduction of 4-hydroxynonenal (4-HNE) adducts and 8-hydroxy-2-deoxyguanosine (8-OHdG) markers of lipid peroxidation and oxidative DNA damage respectively Mitochondrial ROS reduction via Complex IV cuproenzyme enhancement (cytochrome c oxidase activity assay) Epitalons antioxidant activity is primarily documented via melatonin restoration (melatonin is itself a potent radical scavenger) and through modest upregulation of SOD and catalase in aged rodent tissues a secondary effect rather than a primary mechanism
