COSRX The Niacinamide 15 Serum – 20ml
A high-strength, daily-brightening serum with 15% pure niacinamide (vitamin B3) to effectively target enlarged pores, excess oil, acne marks, and uneven skin tone. This lightweight, fast-absorbing formula visibly reduces sebum, clears and refines pores, and fades post-acne discoloration and dark spots for a brighter, clearer complexion. It contains complementary actives—zinc PCA to regulate oil and minimize breakouts, allantoin and panthenol to soothe sensitivity, and acetyl glucosamine for gentle exfoliation and enhanced brightening. Non-sticky and non-irritating, making it suitable even for oily, combination, or blemish-prone skin. With continued use, skin appears smoother, healthier, and more even in tone.
