Anua Niacinamide 10 TXA 4 Serum is a Korean skincare serum formulated with 10% Niacinamide and 4% Tranexamic Acid to support brighter and more balanced-looking skin. The lightweight formula is commonly used in skincare routines targeting uneven skin tone, dullness, and post-acne marks while helping maintain skin hydration and smooth texture. Suitable for oily, combination, and sensitive skin types, it absorbs quickly without a heavy feel.

Many users and skincare reviewers mention improvements in overall skin glow and texture with consistent use, though some people note the formula may feel slightly sticky depending on skin type and layering routine.
