An active, wrinkle-reducing, skin-lifting serum, a collagen booster. Tripeptide-1 is used to stimulate stem cell proliferation, from which cells of various functions, including fibroblasts, are formed. Hexapeptide-12 is a new-generation amino-peptide, composed of three amino acids and an attached palmitic acid. It is precisely due to the latter acid that the peptide can penetrate the skin. The peptide is a fragment of a type I collagen molecule. It acts as a cellular information carrier, stimulating the production of collagen and other main extracellular matrix proteins. Furthermore, hexapeptide-12 is involved in elastin synthesis, resulting in improved skin elasticity when using the serum.
