What is Kojic Acid?
Kojic acid is a fungal-derived compound originally identified in koji, the rice mould used to make sake and miso. It inhibits tyrosinase, the enzyme that catalyses melanin production in skin cells, making it an effective ingredient for fading hyperpigmentation, melasma and post-inflammatory dark spots. It is often paired with niacinamide and vitamin C for synergistic brightening.
