Anua Niacinamide 10% + TXA 4% Serum 30ml

Ten percent niacinamide with four percent tranexamic acid, aimed squarely at dark spots, melasma and the uneven tone that follows sun exposure. Tranexamic acid is one of the few brighteners with real clinical backing on pigmentation in deeper skin. Expect weeks, not days — and wear sunscreen or you are undoing it every morning.
