COSRX serum
The Niacinamide 15 Serum
A surgically precise niacinamide serum — fifteen ingredients, fifteen percent concentration, zero wasted space. The acetyl glucosamine synergy and zinc PCA deliver clinical-grade oil control and brightening that oily skin types will love. But the high concentration isn't for everyone, and the tiny bottle makes the monthly cost hard to ignore.
