Product details

Take total control over breakouts and oily skin with COSRX The Niacinamide 15 Serum. This high-strength, clinical-grade treatment is formulated with a powerful 15% concentration of Niacinamide, the gold standard for refining skin texture. Specifically designed for those struggling with active acne, enlarged pores, and post-inflammatory hyperpigmentation, this serum targets every stage of the breakout cycle. It balances excess sebum, calms inflammation, and smooths out skin irregularities, leaving you with a clear, matte, and healthy-looking complexion.

How to use
Cleanse: After cleansing and toning, apply 2–3 drops to your face and neck.

Target: Focus on areas with active breakouts, blackheads, or excessive oil (like the T-zone).

Absorb: Gently pat with your fingertips until fully absorbed.

Routine: Can be used both morning and night.

Pro Tip: If using in the morning, always follow with a broad-spectrum sunscreen to protect your skin's progress.
Ingredients
15% Niacinamide (Vitamin B3): An ultra-potent concentration that diminishes the appearance of large pores, regulates sebum production, and strengthens the skin's barrier.

N-Acetylglucosamine (NAG): Works in synergy with Niacinamide to gently exfoliate and fade stubborn acne scars and hyperpigmentation.

Zinc PCA: Effectively calms inflammation and prevents bacterial growth, helping to clear up active acne and prevent future flare-ups.

Allantoin: Soothes and protects the skin from irritation, ensuring the high-concentration formula remains comfortable for daily use.

Comprehensive Blemish Care: Targets blackheads, whiteheads, and dark spots all in one bottle.
