Its 15% niacinamide formula is supported by zinc PCA, acetyl glucosamine and allantoin for a combination of oil-conscious care, smoother-looking texture and skin comfort. The lightweight dropper format fits between toner and moisturizer. Introduce it gradually and use a small, controlled amount rather than treating the high concentration as a reason to apply more.\u003c\/p\u003e\u003ch2\u003eCOSRX Niacinamide Serum 101\u003c\/h2\u003e\u003cp\u003eNiacinamide is a form of vitamin B3 widely used in cosmetic skincare. In this serum, the 15% concentration is aimed at visible concerns such as excess oil, uneven-looking tone, pores and blemish marks. It is a leave-on serum, not a cleanser, peel or spot patch.\u003c\/p\u003e\u003cp\u003eCOSRX pairs niacinamide with zinc PCA and acetyl glucosamine, while allantoin adds a skin-comforting element to the formula. The product is designed to be applied across the face after cleansing and toning, rather than only on one spot. A moisturizer still belongs afterward, and daytime sunscreen remains important when you are caring for uneven tone or post-breakout marks.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003ch3\u003eA concentrated niacinamide formula with a lightweight feel\u003c\/h3\u003e\u003cp\u003eThe formula centers on a clearly stated 15% niacinamide concentration, with a supporting blend chosen for oily and uneven-looking skin. Its dropper packaging helps you keep the dose modest and consistent. Although COSRX has tested the finished product for non-comedogenic use, individual tolerance still matters, especially when introducing a concentrated new serum.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15% niacinamide:\u003c\/strong\u003e The main active ingredient supports the appearance of pores, tone and skin texture.

The practical goal is less obvious shine, a more refined-looking surface and a clearer-looking tone over time.
