COSRX The Niacinamide 15 Serum 20ml is a concentrated facial serum formulated with 15% Niacinamide to help control excess sebum, minimize the appearance of enlarged pores, and improve uneven skin tone. Its lightweight texture absorbs easily into the skin, making it suitable for skincare routines focused on oily skin, visible pores, blemishes, and post-acne marks.

The formula combines Zinc PCA and N-Acetylglucosamine (NAG) to help regulate excess oil and improve the appearance of uneven texture, while Allantoin helps soothe and condition the skin.
