Safety Guide
Evidence-based safety information for using Kojic Acid for rosacea-prone skin.
Kojic Acid is flagged as potentially irritating for sensitive skin, which includes rosacea. Use with caution and patch test.
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.
