COSRX The Niacinamide 15 Serum 20ml is a concentrated brightening serum formulated with 15% Niacinamide to help improve the appearance of uneven skin tone, minimize the look of pores, and balance excess oil for a clearer complexion. Its lightweight texture absorbs quickly without leaving a sticky finish.

Enriched with Zinc PCA, Acetyl Glucosamine, Trehalose, Allantoin, and Vitamin E, it helps soothe the skin, maintain moisture, and support a healthy skin barrier while promoting smoother, more refined skin.

Suitable for all skin types, especially oily and blemish-prone skin. Apply a few drops to the face after cleansing and toning, then gently pat until fully absorbed.
