MSRP $28 WHAT IT DOES: One of the most research-supported anti-aging ingredients in skincare. The vivid blue color comes from the chemical bond between the tripeptide (glycyl-L-histidyl-L-lysine) and copper ions — this bond drives tissue repair and collagen production. Benefits: stimulates collagen and elastin (reducing fine lines); accelerates skin repair and regeneration; provides antioxidant protection; improves firmness and texture. In a 12-week clinical study,70% of women using GHK-Cu showed improved collagen — outperforming both vitamin C (50%) and retinoic acid (40%). BEST FOR: Anyone targeting fine lines, loss of firmness, or aging/damaged skin. IMPORTANT NOTE: Do NOT layer with vitamin C or AHA/acid products simultaneously. Copper peptides are proteins that destabilize when mixed with acids or vitamin C. Use separately — one in the morning, the other at night
