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.
In terms of concentration for visible results, the recommended amount to use is between 0.4–2% of this blend. Since both amino acids making up this peptide are found naturally in skin, arginine/lysine polypeptide is considered safe and non-irritating.
