Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A combined INCI of designer tripeptide-117 with the amino acid citrulline, used for skin conditioning. Citrulline is well-tolerated; the peptide has limited independent data.
This combination INCI represents a supplier blend of designer Tripeptide-117 with the free amino acid citrulline (a non-protein amino acid involved in nitric oxide pathways). Citrulline is widely used in cosmetics and oral supplements with a strong safety record. The tripeptide component is proprietary, used at trace ppm levels, with no independent CIR or SCCS review. The blend is intended for skin-conditioning effects. Conservative tier: yellow with low evidence — citrulline pulls slightly upward, the unknown peptide pulls back.
