KOJ
8/10
Concern level
High concern

A kojic-acid-derived cinnamate used primarily as an antioxidant in cosmetic formulations. It helps limit oxidation of formula ingredients and is often included in leave-on products such as serums, creams, and eye care. Public ingredient references describe it as an antioxidant rather than a primary treatment active, and available listings suggest it is used at low levels in finished products.

Risks & Warnings
