Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A synthetic seven-amino-acid peptide used as a skin-conditioning agent. Designer peptide with little independent safety or efficacy data.
Heptapeptide-55 is a seven-residue synthetic peptide developed for cosmetic skin-conditioning use. Like most modern designer heptapeptides it is supplied as a dilute solution and used at parts-per-million concentrations in serums and creams. The class is generally regarded as low-risk because of poor penetration and rapid degradation, but Heptapeptide-55 itself lacks an independent CIR or SCCS review. Listed in EU CosIng. Conservative classification is yellow with low evidence pending independent data.
