About

A synthetic peptide conjugate with moderate uncertainty because the aromatic active makes it less straightforward than a simple peptide.

METHYLENEDIOXYPHENYLSUCCINOYL NONAPEPTIDE-18 is a peptide linked to an aromatic small-molecule fragment for targeted cosmetic activity. Peptide size helps limit penetration, but the conjugated aromatic portion makes the toxicology less routine than that of plain signal peptides and public data for this exact ingredient are sparse. That supports a cautious middle score.
