Safety Guide
Evidence-based safety information for using Kojic Acid for sensitive and reactive skin.
Kojic Acid is flagged as potentially problematic for sensitive skin. Consider gentler alternatives or use with extreme caution.
Kojic acid is a potent tyrosinase inhibitor derived from fungi, used extensively in Asian skincare for hyperpigmentation. It's more effective than many natural brighteners but less stable and more irritating than niacinamide — a trade-off that makes it best suited for targeted use rather than daily application.
