The COSRX Niacinamide 15% Face Serum comes in a compact 0.67 fl.oz/20 ml bottle, making it travel-friendly and convenient to use. The packaging is sleek and modern, reflecting the brand’s commitment to simple yet effective skincare solutions.

With a high concentration of 15% Niacinamide, this serum effectively minimizes enlarged pores, reduces excess oil production, and improves skin texture. The addition of Zinc PCA at 1% further helps prevent potential breakouts. These dermatological ingredients work together to refine uneven skin tone and promote a more radiant complexion.
