Kojic Acid
Check a product label in the checker
What the ingredient tells you
Kojic acid is used in some products aimed at pigmentation. DermNet notes that it may cause irritant or allergic contact dermatitis. Its presence is not a promise that a product will fade a mark.
Using the finished product
Follow the product's directions and sun-protection advice. Ask a clinician about changing marks or persistent pigmentation, rather than trying to identify a condition from a label.
Compatibility and tolerance
A combined product is not automatically well tolerated because a formulator made it. Adding exfoliants may increase irritation. Ask your clinician about use during pregnancy or nursing.
