About R-(METHIONYL SH-POLYPEPTIDE-31 DECAPEPTIDE-40)
A biotech peptide active with more uncertainty than a simple moisturizer, though limited skin penetration keeps risk below the worst cases.
Detailed Analysis
R-(METHIONYL SH-POLYPEPTIDE-31 DECAPEPTIDE-40) is a recombinant protein or fusion peptide produced by fermentation for skin-conditioning or protective claims. Large proteins usually penetrate intact skin poorly, but this is still a biologically complex, less-established ingredient class than ordinary emollients or humectants. The main concern is limited independent long-term cosmetic safety data.
