Palmitoyl Tetrapeptide-7 (Rigin) is published as an anti-inflammatory cosmetic peptide that modulates IL-6 and helps protect newly synthesized matrix in Matrixyl 3000-style formulas. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
