This anti-freckle serum contains two core ingredients: niacinamide and tranexamic acid. Niacinamide can inhibit the production of melanin and reduce the formation of spots. Tranexamic acid can effectively decompose the formed melanin and lighten the spots. It can act precisely on the spots and improve the dullness of the skin. The texture is clear and easily absorbed by the skin. Suitable for a variety of skin types, continuous use can make the skin brighter and more even-toned, and reduce the trouble of spots.
