Cosrx - Serum - The Niacinamide 15 Serum

COSRX Niacinamide 15 Serum is a highly concentrated treatment specially formulated to effectively combat acne, excess sebum, and dark spots. Thanks to its high niacinamide content (15%), it soothes blemishes, tightens pores, and regulates sebum production, while N-acetylglucosamine gently exfoliates and helps fade hyperpigmentation. Enriched with zinc PCA, it rebalances the skin, reduces inflammation, and promotes skin repair, leaving the skin smoother, clearer, and visibly improved, regardless of skin type.
