The Cosrx Niacinamide Serum is designed for people who struggle with excess oil, visible pores, and recurring breakouts. It delivers a 15% concentration of niacinamide, which is known for regulating sebum, refining skin texture, and improving clarity over time. As a result, the skin appears smoother, less shiny, and more stable after continuous use.
Unlike harsh anti-acne treatments that dry out the skin, this serum works while preserving balance. In addition, it helps calm visible redness and irritation that often accompany oily or congested skin. The formula also assists in preventing new blemishes by keeping the surface clean and regulated.
With regular application, the serum not only reduces oil production but also improves post-blemish marks and uneven tone. Moreover, its lightweight texture absorbs easily without clogging pores or leaving residue. Ultimately, the Cosrx Niacinamide Serum functions as a targeted solution for those wanting long-term pore control and clearer skin without compromising comfort.
