A closer look

What the research shows

Safety assessment

The panel accepted the described cosmetic uses after reviewing toxicology and relevant medical-device evidence.

What this does not tell us

Published safety assessment, not an efficacy trial. Its conclusion is limited to the reported cosmetic uses and concentrations, and relies partly on group read-across where individual data are missing. It does not establish current regulatory status or guarantee tolerance for every formulation. Medical-device evidence contributes to the assessment, but does not establish a cosmetic benefit. Particle properties and exposure conditions matter.
