COSRX The Niacinamide 15 Serum
Target excess oil, visible pores, post-breakout marks, and uneven texture with COSRX The Niacinamide 15 Serum, a high-strength daily serum designed to help refine and balance blemish-prone skin while leaving it smoother, clearer, and more even-looking.
Formulated with 15% niacinamide, zinc PCA, N-acetylglucosamine, and allantoin, this lightweight serum helps support total breakout care and oil control. Niacinamide helps reduce the look of excess shine, enlarged pores, and uneven tone, while zinc PCA helps support sebum balance for a fresher, less greasy-looking complexion. N-acetylglucosamine helps improve the appearance of post-acne marks and rough texture, while allantoin helps comfort and soothe the skin.
This serum is a great choice for anyone looking for a K-beauty niacinamide serum, oil-control serum, or a pore-refining serum for acne-prone skin. Its fast-absorbing, non-heavy texture makes it easy to layer into both morning and evening routines for skin that looks clearer, smoother, and more balanced over time.
