COSRX - The Niacinmaide 15 Serum

Pores blurred. Oil balanced. Skin instantly cleaner-looking.

This high-performance serum is powered by 15% Niacinamide to visibly tighten pores, control excess oil, and improve uneven texture — without stripping or over-drying the skin.

The formula goes beyond niacinamide. Zinc PCA helps regulate sebum and calm breakouts, while N-Acetyl Glucosamine (NAG) supports brighter, smoother skin and enhances tone clarity. Lightweight, fast-absorbing, and shine-free, this serum is made for skin that wants results, not excuses.
