COSRX Niacinamide 15 Serum

COSRX Niacinamide 15 Serum is a high-strength brightening and blemish-control serum designed for oily and combination skin in Bangladesh. It uses 15% niacinamide to visibly reduce excess sebum, minimize enlarged pores, and fade post-acne marks and hyperpigmentation. The lightweight, fast-absorbing texture layers easily under moisturizer and sunscreen without pilling. It helps strengthen the skin barrier while calming redness and improving overall skin clarity. Regular use supports smoother texture, fewer breakouts, and a more even tone. Suitable for humid climates, it keeps skin balanced without heavy residue. Apply after cleansing and toning, before heavier creams. For best results, use consistently and pair with broad-spectrum sunscreen daily. This formula is fragrance-light and suitable for most skin types, especially oily and acne-prone. Always patch test before first use and introduce gradually if you are new to high-percentage niacinamide.
