Formulated with Matrixyl 3000 and Argirelox peptides, this serum regulates the skin from within to produce a firmer, smoother texture. Matrixyl 3000 is an anti-aging formula that combines palmitoyl tetrapeptide-1 (Pal-GHK) and palmitoyl tripeptide-7 (Pal-GQPR). These peptides are composed of amino acids and fatty acids and have been gaining attention for their synergistic ability to firm the skin and lock in hydration. Argirelox is a new formulation of Argireline Peptide, a well known anti-aging component. Blended with Acetyl Hexapeptide-8 and Pentapeptide-18 (Leuphasyl), this well balanced formulation stimulates the skin from within the stratum corneum to produce a firmer and smoother texture, leading a more youthful appearance.
