Anua Niacinamide 10 + TXA 4% Serum

At 10% niacinamide and 4% tranexamic acid, this serum stacks two of the most clinically validated brightening actives available, and the addition of alpha-arbutin and 3-O-ethyl ascorbic acid makes the case for brightening even stronger. It delivers exactly what a serum in this category should.
