The Purito Seoul TXA 6 Niacinamide 10 Retinal Serum is a lightweight, triple-action treatment designed to fade dark spots, brighten uneven skin tone, and smooth fine lines. This formula combines a powerful concentration of 10% Niacinamide for brightening and barrier support with 6% Tranexamic Acid (TXA) to effectively fade dark spots and discoloration. The third main ingredient is Encapsulated Retinal, an advanced form of Vitamin A that works much faster than retinol to promote cell renewal, reduce fine lines, and improve skin texture with less irritation.
