Total Acne Control with Maximum-Strength Niacinamide

The COSRX The Niacinamide 15 Serum is a highly concentrated treatment serum formulated with 15% Niacinamide — the maximum effective concentration — combined with synergistic ingredients at optimal ratios for comprehensive acne control. It targets breakouts, excess sebum, enlarged pores, and post-acne marks all in one lightweight, fast-absorbing formula.

Key Benefits

  • 15% Niacinamide regulates sebum production to reduce shine and prevent breakouts
  • Minimizes the appearance of enlarged pores for a smoother, more refined skin texture
  • Fades post-acne marks and hyperpigmentation for a more even skin tone
  • Strengthens the skin barrier to reduce sensitivity and prevent future blemishes
  • Lightweight, non-greasy texture suitable for oily, combination, and acne-prone skin

What's Inside

20ml — a concentrated total acne-control serum for visibly clearer, more balanced skin.

How to Use

Step 1: After cleansing and toning, allow your skin to fully absorb the toner before applying the serum. Step 2: Dispense a few drops of the serum onto your fingertips. Apply directly to problem areas such as blemishes, enlarged pores, or oily zones — or spread evenly across the entire face. Step 3: Gently pat the serum into the skin with your fingertips until fully absorbed. Do not rub. Step 4: Follow with your moisturizer to seal in the serum and support the skin barrier. Step 5: In the morning, always finish with SPF 30 or higher to protect your skin and maintain your results. *Patch test recommended before first facial use. *For external use only. If irritation occurs, discontinue use and consult a dermatologist.
