Matrixyl S6 Serum contains Matrixyl Synthe'6, a powerful peptide that boosts six skin-rebuilding essentials. This anti-wrinkle complex helps reverse the signs of aging by stimulating six major constituents of the skin matrix and dermal-epidermal junction (collagen I, II, IV, fibronectin, hyaluronic acid and lamin 5). Evens out skin and smoothes wrinkles from the inside by rebuilding the skin where it is needed, particularly on the forehead and crow's feet.
