Reveal Clearer, Smoother, and Healthier Skin

Struggling with oily skin, enlarged pores, or stubborn acne? COSRX The Niacinamide 15 Serum is a high-performance formula designed to combat all stages of acne while refining your skin texture. With a potent 15% niacinamide concentration, this powerhouse serum works to control excess sebum, minimize pores, and brighten uneven skin tone—leaving your skin smooth, radiant, and refreshed.

Why Choose COSRX The Niacinamide 15 Serum?

✅ High-Potency 15% Niacinamide

Niacinamide (Vitamin B3) at a high concentration of 15% helps regulate sebum production, making it a game-changer for oily and combination skin types. It also works to fade acne scars, reduce redness, and even out skin tone over time.

✅ Acne Care at Every Stage

Unlike other serums, this formula targets all stages of acne—from prevention to treatment and post-acne healing. It soothes existing breakouts while preventing future ones from appearing.

✅ Pore-Minimizing & Oil Control

Enlarged pores? Excessive oiliness? This serum tightens pores and balances sebum levels, leaving your skin feeling fresh without greasy residue.

✅ Brightening & Hyperpigmentation Care

Tired of dull skin and acne marks? Niacinamide, along with Acetyl Glucosamine, Zinc PCA, and Tocopherol (Vitamin E), helps fade dark spots and promote a brighter, more radiant complexion.

✅ Lightweight & Non-Sticky Formula

No heavy, greasy feel! The light and refreshing texture absorbs quickly into the skin, making it perfect for layering under other skincare products or makeup.

✅ Morning & Evening Use

Unlike highly concentrated serums that can only be used at night, COSRX The Niacinamide 15 Serum is gentle enough for both morning and evening use. Just make sure to follow up with SPF 30+ during the day!
