Medik8 Copper PCA Peptides is a skincare product that combines the benefits of copper, PCA (pyrrolidone carboxylic acid), and peptides. Copper promotes collagen production, improves elasticity, and provides antioxidant protection. PCA helps to maintain skin hydration by attracting and holding moisture. Peptides are small proteins that support skin repair and rejuvenation. Together, these ingredients work synergistically to enhance skin health, reduce signs of aging, and promote a more youthful complexion.
