Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A combined INCI of two designer oligopeptides (oligopeptide-221 with oligopeptide-133) used for skin conditioning. Limited independent safety data.
This is a combination INCI representing a supplier blend of oligopeptide-221 and oligopeptide-133, both multi-residue synthetic peptides formulated for skin-conditioning cosmetic use. Such combination INCIs are typical of proprietary designer peptide actives sold as ready-to-use solutions. Use levels are at parts-per-million in serums and creams. Neither component has an independent CIR or SCCS review; combination performance relies on supplier studies. Conservative tier: yellow with low evidence; combining two unknowns warrants extra caution.
