The product
The COSRX The Niacinamide 15 Serum is your skin savior if you struggle with oily skin, acne, or dark spots. This powerful serum contains no less than 15% Niacinamide, one of the most loved skincare ingredients to even out the complexion, regulate sebum production, and reduce breakouts. And that’s not all – it also helps fade pigmentation and calm inflammation.
The formula is enhanced with N-acetylglucosamine (NAG), an ingredient that gently exfoliates the skin for a smooth, fresh-looking complexion. Additionally, Zinc PCA helps reduce redness and rebalance the skin. The result? A clear, healthy complexion with less shine and fewer blemishes. Perfect for oily, combination, and acne-prone skin that could use some extra care.
