Combining glutathione, kojic acid and niacinamide creates a powerful, science-backed formulation for targeting uneven skin tone, dark spots and overall radiance. Each ingredient works through a distinct mechanism, and together they offer a comprehensive approach to brightening. Kojic acid and glutathione stop the production of melanin while niacinamide prevents that pigment from reaching the skin's surface — so dark spots fade and new ones are blocked from forming. Glutathione is also a powerful antioxidant, and niacinamide helps regenerate it, creating a shield against environmental damage. Beyond brightening, niacinamide strengthens the skin barrier, improves hydration and smooths texture for resilient, healthy-looking skin.
