Target breakouts, excess oil, and uneven skin tone with COSRX The Niacinamide 15 Serum, a highly concentrated formula designed for comprehensive acne care. Featuring 15% niacinamide blended with synergistic ingredients—N-acetylglucosamine, zinc PCA, and allantoin—this serum works to calm inflammation, regulate sebum production, visibly fade dark spots, refine rough texture, and support skin regeneration.

Lightweight and watery, it absorbs quickly to leave skin refreshed, hydrated, and never greasy. Clinically tested to deliver results in as little as four weeks, the formula is non-comedogenic and ideal for oily, combination, and acne-prone skin types dealing with enlarged pores, dullness, and congestion.

Crafted with COSRX’s signature minimal-ingredient philosophy, this Korean-made, cruelty-free serum provides targeted, effective, and gentle care for every stage of acne.

Key Ingredients: Water, Pentylene Glycol, Niacinamide(15%), Butylene Glycol, Acetyl Glucosamine, 1,2-Hexanediol, Zinc PCA, Trehalose, Xanthan Gum, Pullulan, Allantoin, Ethylhexylglycerin, Sodium Phytate, Citric Acid, Tocopherol
