Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A synthetic three-amino-acid peptide used as a skin-conditioning agent. Designer tripeptide with limited public safety/efficacy literature.
Tripeptide-105 is a three-residue synthetic peptide developed for cosmetic skin-conditioning use. Tripeptides are among the smallest signal peptides in cosmetic use, generally well-tolerated at the parts-per-million doses typical of leave-on formulas. The very small size also means rapid enzymatic turnover on skin. No CIR or SCCS review is available for this specific INCI; efficacy claims rely on supplier-sponsored testing. Listed in EU CosIng. Conservative tier: yellow with low evidence.
