Multi-Technology Peptide Serum. This formula combines a comprehensive array of studied technologies to target multiple signs of aging at once. The technologies are Matrixyl™ 3000 peptide complex (with palmitoyl tetrapeptide-7), Matrixyl™ synthe'6™ peptide complex (with palmitoyl tripeptide-38), SYN™-AKE peptide complex (with dipeptide diaminobutyroyl benzylamide diacetate), Relistase peptide complex (with acetylarginyltryptophyl diphenylglycine), ARGIRELOX™ peptide complex (with acetyl hexapeptide-8, pentapeptide-18), Probiotic complex (with lactococcus lactis lysate), in a base of 11 skin-friendly amino acids and multiple hyaluronic acid complexes. The total concentration of these technologies in the formula by weight is 25.1%. *Note: 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.
