The Ordinary Matrixyl 10% and HA Peptide Formulation offers an advanced formula that targets fine lines and wrinkles by promoting firmer, plumper skin. With two generations of MatrixylTM and hyaluronic acid, this lightweight serum improves the appearance of facial areas prone to fine lines by supporting your skin’s overall collagen production. Matrixyl is a trademarked peptide composition developed by Sederma Inc in France. This highly effective composition has been shown to reduce the look of static and dynamic wrinkles. This formula contains two generations of Matrixyl, Matrixyl 3000 and Matrixyl synthe'6, at a combined concentration of 10% by weight in a specialized Hyaluronic Acid delivery system. The peptide in Matrixyl 3000 is palmitoyl tetrapeptide 7 and the peptide in Matrixyl synthe'6 is palmitoyl tripeptide 38. It is best to not use Peptides in the same routine as the following products: Direct acids, LAA (L-Ascorbic Acid) and ELAA (Ethylated Ascorbic Acid). In addition, we would recommend avoiding the use of products containing copper peptides in the same routine as strong antioxidants as well as direct acids/LAA/ELAA.
