Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A synthetic five-amino-acid peptide used as a skin-conditioning active. Low-risk by class; specific evidence is thin.

Pentapeptide-31 is a defined-sequence synthetic five-amino-acid peptide used as a skin-conditioning agent. Pentapeptides have a generally favorable safety profile in cosmetic use — too large for efficient deep penetration, broken down to amino acids by skin proteases, low sensitization risk. No CIR or SCCS opinion exists. Independent peer-reviewed efficacy data is essentially absent; claims rely on supplier in vitro work.
