Who Is This Product For?

This serum is particularly relevant for oily, combination and blemish-prone skin, especially when excess shine, visible pores or lingering post-acne marks are concerns.

Because 15% Niacinamide is a concentrated formula, sensitive-skin users and beginners should introduce it cautiously.

How to Use

After cleansing and optional toner, apply a few drops evenly to the face. Gently massage until absorbed, then follow with moisturizer.

Start gradually if new to concentrated Niacinamide. COSRX allows morning or evening application. During daytime use, finish with broad-spectrum SPF 30+ sunscreen.
