Arginine/Lysine Polypeptide Excellent Peptide Anti-âge Hydratation Arginine/Lysine Polypeptide at a glance A multi-peptide blend that supports skin’s collagen and elastin Helps offset substances within skin that break down collagen Lab-synthesized for precise, consistent results + stability Topical use helps restore a firmer look and feel Arginine/Lysine Polypeptide description Arginine/lysine polypeptide is a lab-synthesized multi-peptide based on the skin-friendly amino acids l-arginine and l-lysine. These amino acids are known as oligopeptides, which are smaller peptide chains of at least two (but not more than 20) amino acids. Studies from the supplier of this ingredient indicate it helps to preserve skin’s natural collagen and elastin by offsetting substances within skin that cause both to degrade over time. Peptides with arginine are considered carrier peptides since they can improve topical delivery of ingredients, while lysine-based peptides generally have signaling qualities. Since both amino acids making up this peptide are found naturally in skin, arginine/lysine polypeptide is considered safe and non-irritating. Related ingredients: Arginine Lysine Peptides
