How does Kojic Acid help in treating different skin conditions? Kojic Acid can help treat specific skin conditions like-
  • Hyperpigmentation- Kojic Acid helps treat hyperpigmentation by acting as a tyrosinase inhibitor. It helps reduce the amount of melanin produced and helps get rid of hyperpigmentation with consistent usage.
  • Dark spots- Due to its antioxidant properties, Kojic Acid can help protect the skin from certain kinds of damage and may help prevent the appearance of signs of aging such as dark spots and fine lines. It’s ability to decrease melanin synthesis is also effective against dark spots.
