[COSRX] The Niacinamide 15 Serum (20ml) – Total Acne & Pore Refining Solution

Product Overview: Take control of breakouts and excess oil with the COSRX The Niacinamide 15 Serum. This 20ml high-potency treatment combines a maximum concentration of 15% Niacinamide with Zinc PCA to deeply refine pores and regulate sebum production. Designed for oily, combination, and acne-prone skin, it addresses all stages of acne—from initial inflammation to post-breakout marks. The lightweight, non-comedogenic formula absorbs instantly without a tacky residue, helping to smooth rough texture and brighten hyperpigmentation. Clinical results show a 50% reduction in whiteheads and a 48% improvement in oiliness after 4 weeks of use, revealing a clearer and more balanced complexion.

Key Features & Benefits:

15% High-Concentration Niacinamide: Effectively balances sebum, minimizes enlarged pores, and fades post-acne dark spots.

Zinc PCA: Inhibits inflammation and promotes the recovery of damaged skin while controlling excess oil.

N-Acetylglucosamine (NAG): Works in synergy with niacinamide to gently exfoliate and effectively reduce hyperpigmentation.

Allantoin & Squalane: Help to soothe sensitivity and maintain the skin's moisture balance to prevent dryness.

Pore & Texture Refining: Clinically proven to reduce the appearance of blackheads and whiteheads while smoothing skin bumps.

Fast-Absorbing & Non-Greasy: A fresh, watery texture that layers perfectly under other skincare products or makeup.

How to Use:

After cleansing and toning, apply a few drops to the face.

Gently massage into the skin with fingertips, starting from the center and moving outwards.

Pay extra attention to the T-zone or areas with visible pores and breakouts.

Tip: For best results, use morning and night. If used in the morning, always follow up with a broad-spectrum sunscreen.
