The COSRX The Niacinamide 15 Serum is a highly-concentrated serum that combines the maximum concentration of niacinamide with optimal ratios of synergistic ingredients for total acne and dark spots control. This serum also contains N-acetylglucosamine (NAG) to gently exfoliate skin and fade hyperpigmentation, while zinc PCA balances skin's oil-water levels.
Suitable for all skin types, recommended for oily and acne skin.
