Kojic Acid anchors this professional depigmentation system, blocking tyrosinase enzyme activity to visibly reduce dark spots and hyperpigmentation. Ascorbic Acid brightens skin tone whilst providing antioxidant defence, Arbutin works as a natural tyrosinase inhibitor to even out discolouration, and Azelaic Acid reduces pigmentation whilst calming inflammation. Titanium Dioxide delivers broad-spectrum mineral sun protection to prevent UV-induced pigmentation rebound. The formula is dermatologist-tested, non-comedogenic, and suitable for all skin phototypes.
