COSRX The Niacinamide 15 Serum 20ml

Product Description

A high-strength 15% Niacinamide serum aimed at uneven tone, visible pores and rough texture in one concentrated step.

Niacinamide is one of the most versatile actives in skincare, working on multiple concerns at once without the irritation risk of stronger acids or retinoids. At this concentration, it's best introduced gradually, a few times a week at first, before working up to daily use as skin adjusts. Over time, pores look smaller, tone appears more even and texture feels noticeably smoother.
