Description

COSRX The Niacinamide 15 Serum is a potent formulation designed to tackle acne at its roots, specifically crafted for those with oily and acne-prone skin types. With a high concentration of 15% niacinamide, this serum is a powerhouse in controlling acne, reducing sebum production, and soothing inflammation. It plays a crucial role in minimizing the visibility of acne scars, leaving your skin clearer and more refined.

The inclusion of acetyl glucosamine, allantoin, and zinc enhances the serum’s effectiveness, offering a comprehensive approach to acne care. This multifunctional serum not only targets breakouts but also works diligently to fade dark spots and hyperpigmentation, while exfoliating dead skin cells to improve skin texture. Its lightweight formula ensures easy absorption without clogging pores, effectively tightening them and reducing their appearance.
