Concern level

High concern

Cetyl Tranexamate Mesylate is a synthetic tranexamic-acid derivative used in skincare as a skin-conditioning and brightening ingredient. Cosmetic sources describe it as a tranexamic-acid-based molecule with a cetyl chain, intended to improve the appearance of uneven tone and post-inflammatory discoloration while being more lipophilic than tranexamic acid itself.

Risks & Warnings

Because it is a newer cosmetic ingredient, robust published safety dossiers are sparse compared with older actives.
