About the Product

The COSRX The Niacinamide 15 Serum is a highly concentrated solution designed to combat breakouts, excess oil, and post-acne marks. Infused with 15% niacinamide, this potent formula regulates sebum production, refines pores, and brightens uneven skin tone. It also contains acetyl glucosamine, which works synergistically with niacinamide to fade dark spots and improve overall clarity. Zinc PCA provides additional oil-control benefits while reducing inflammation, making it ideal for acne-prone and congested skin. Despite its strength, the serum is lightweight, fast-absorbing, and suitable for daily use, helping skin look clearer, smoother, and more balanced over time.

How to Use

After cleansing and toning, apply 2–3 drops to areas of concern or the entire face. Gently pat until fully absorbed, then follow with a moisturizer. Use daily, morning and night. Always apply sunscreen when using brightening treatments in the daytime.
