Anua Niacinamide 10% + TXA 4% Dark Spot Correcting Serum  10ml is a lightweight, non-sticky watery serum which treats stubborn dark spots and uneven skin tone. Formulated with 10% Niacinamide, 4% Tranexamic Acid and 2% Arbutin, this potent combination of key active ingredients combats dull skin and minimises the appearance of enlarged pores. The 10% Niacinamide content helps to even out skin tone for clearer skin and helps to reduce discolouration by breaking down excess Melanin. The 4% TXA element together with 2% Arbutin visibly fades existing dark spots and prevents the formation of new ones by interrupting Melanin production
