Description
Multi-Tasking Serum with 15% Niacinamide for a More Even, Balanced Skin
The COSRX The Niacinamide 15 Serum is a powerful, lightweight formula specially developed for skin with excess oil, visible pores, uneven tone, or post-acne marks. Thanks to a high concentration of 15% niacinamide, combined with zinc PCA and N-acetylglucosamine, this serum helps regulate sebum production, refine pores, reduce redness and blemishes, and improve overall skin texture. The formula absorbs quickly, feels comfortable on the skin, and leaves the complexion calmer and more balanced.
Key Benefits
Regulates sebum production and reduces shine
Niacinamide and zinc PCA work together to reduce excess oil and help control shine.
Refines pores and improves skin texture
Less visible pores, a smoother surface, and a more even complexion thanks to the power of niacinamide and supportive ingredients.
Soothes and supports skin recovery
Allantoin and other caring ingredients help calm redness and support skin repair.
Lightweight and fast-absorbing
Absorbs quickly without leaving a sticky or heavy layer, making it ideal under your skincare routine.
Suitable for oily, combination, and blemish-prone skin types
Helps target specific skin concerns without drying out the skin.
How to use
Apply a few drops to cleansed skin (face and neck) in the morning and/or evening. Gently pat or massage until fully absorbed. Follow with a moisturizer. During the day, always combine with sun protection (SPF).
