Multi-Technology Peptide Serum. This formula combines a comprehensive array of studied technologies to target multiple signs of aging at once. The technologies are direct Copper Peptides, also known as GHK-Cu (Copper Tripeptide-1), 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) and a Probiotic complex (with Lactococcus lactis lysate), solubilized in a base of 11 skin-friendly amino acids and multiple forms of hyaluronic acid. The "Buffet" + Copper Peptides 1% formula differs from the original "Buffet" as this formula includes a 1% concentration of pure Copper Peptides, increasing its focus on overall skin health. The natural role of these peptides as found in human plasma includes supporting a wide range of skin health functions like maintaining normal immune function, collagen synthesis, fibroblast production and anti-inflammatory responses. The inclusion of Copper Peptides offers a natural blue tint to the formula. The total concentration of active technologies in this formula is 26.1%. *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.
