This 15% niacinamide serum helps minimize pore size, improve skin texture, and fade dark spots. Formulated with zinc PCA to reduce excess oil and enhance radiance.

Review: Smooth - Cosrx serum I must say, is hands down the best facial serum I’ve ever used. From the first application, I noticed how smooth and refreshing it felt on my skin. It absorbs quickly, leaves no sticky residue, and gives my face such a healthy, radiant glow. Honestly, I wish I could buy it in dozens — like a pack of twelve — just to make sure I never run out. That’s how much I love it. If you're looking for a serum that truly delivers, this is the one.

### ⭐⭐⭐⭐⭐ Works well
*by L***E on 7 January 2026*

Helps with acne

### ⭐⭐⭐⭐ Good stuff
*by A***Y on 25 July 2025*

Helped improve my skin texture over 3-4 months of usage. Go easy, a tiny drop is good enough for one cheek. Spreads easily. Also I don’t use it every night, it can make your skin slightly dry. Put a layer of moisturiser on top. This product has helped to clear my pores and minimised their appearance. I have oily T-zone.
