The COSRX Niacinamide 15 Serum (The Niacinamide 15 Serum) is a concentrated 15% niacinamide serum that targets uneven tone, visible pores and excess oil, helping skin look clearer, brighter and more balanced.
Its lightweight water-gel texture absorbs quickly without a sticky residue, while trehalose adds comfortable hydration. Zinc PCA supports oil balance, making it a great match for oily and blemish-prone skin that also wants a more radiant, even complexion.
All skin types, especially oily, combination or blemish-prone skin with uneven tone or visible pores.
After cleansing and toning, apply a few drops to the face and gently pat to help absorption. Follow with moisturizer. Use morning or evening, with sunscreen during the day.
