Kojic acid is renowned for evening out skin tone, first and foremost. By suppressing melanin overproduction in the skin, says aesthetic doctor Dr Ana Mansouri, “it effectively targets hyperpigmentation caused by sun damage and acne marks.” It also acts as an antioxidant.
In addition to skin-lightening effects, kojic acid also contains some antimicrobial properties. It may help fight off several common types of bacterial strains even in small dilutions. This can help treat acne caused by bacteria in the skin. It may also lighten scars from acne that haven't faded yet.
