COSRX The Niacinamide 15 Serum is a high-strength Korean skincare serum specially formulated to target acne, excess oil, enlarged pores, uneven skin tone, and dullness. With a powerful 15% Niacinamide concentration, this serum works effectively to balance sebum production, refine pores, and improve overall skin clarity.

Niacinamide (Vitamin B3) is a clinically proven ingredient known for its ability to control oil, reduce blemishes, fade dark spots, and strengthen the skin barrier. This serum also helps calm inflamed skin, making it an excellent choice for acne-prone and oily skin types.

The lightweight, fast-absorbing texture penetrates deeply into the skin without leaving any sticky or greasy residue. It layers well under moisturizers and sunscreen, making it suitable for both morning and night routines.

COSRX The Niacinamide 15 Serum is enriched with zinc PCA and allantoin, which help soothe irritation, control breakouts, and maintain skin comfort even with regular use. With consistent application, the skin appears clearer, smoother, and more balanced.

This serum is suitable for oily, combination, acne-prone, and normal skin types. Sensitive skin users can also use it by starting slowly and patch testing due to its high concentration.

The 20ml size is perfect for targeted treatment, trial use, or travel, while still delivering visible results.
