Product description

A powerful niacinamide serum that helps balance oil, clear blemishes and refine the look of pores.

COSRX The Niacinamide 15 Serum is a concentrated treatment formulated to address congestion, excess sebum and uneven skin tone. With 15% niacinamide, this serum helps regulate oil production, minimise the appearance of pores and reduce redness associated with breakouts. The formula works to support a clearer, smoother complexion while enhancing the skin’s natural barrier function.

Despite its high strength, the lightweight serum absorbs quickly and layers comfortably with other skincare products. Ideal for oily, combination and blemish-prone skin, it helps improve clarity and texture with regular use. Over time, the complexion appears more balanced, refined and visibly brighter.
