Medik8 Copper Pca Peptides is the product that effectively protects your skin against free radicals. Free radicals react with skin cells and cause damage, which ultimately leads to premature skin aging. Copper PCA peptides is a patented ingredient whose antioxidant effect is 40 times more powerful than that of vitamin C. Copper PCA peptides, together with other antioxidant ingredients (such as vitamin E and superoxide dismutase), neutralize free radicals and prevent skin cells from being damaged. Vitamin E can regenerate the antioxidants in the formula, for optimal functioning. A skin-rejuvenating complex of various peptides stimulates collagen production, to firm and lift the skin. The special packaging contains 2 components. This prevents the ingredients from being mixed too early and losing their effect. A powerful and effective formula is thus guaranteed!
