COSRX Niacinamide 15 Serum is a targeted solution for oily, acne-prone, and uneven skin. With a powerful 15% concentration of niacinamide, it regulates sebum, fades post-acne marks, and visibly tightens pores.

The lightweight texture absorbs quickly without residue, making it ideal for layering under other skincare. Dermatologist-tested and non-comedogenic, it’s a daily essential for clearer, smoother skin.
