Restore your skin's lost radiance and balance. The Anua Niacinamide 10% + TXA 4% Dark Spot Correcting Serum will give it the hydration and brightness it needs. It contains three active ingredients – niacinamide, tranexamic acid, and arbutin, which ensure the skin looks smooth and even. The lightweight, water-based texture is easily absorbed and does not leave an unpleasant greasy feeling.
