Shipping options and eligibility are confirmed at checkout.
COSRX The Niacinamide 15 Serum is a concentrated 20mL facial serum for oily, blemish-prone skin and the appearance of enlarged pores. 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.

Niacinamide 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.
COSRX 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.
A concentrated niacinamide formula with a lightweight feel
The 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.
- 15% niacinamide: The main active ingredient supports the appearance of pores, tone and skin texture. This high-concentration formula is distinct from a basic moisturizer that happens to contain a smaller, unspecified amount of niacinamide.
- Zinc PCA support: Zinc PCA complements the oil-conscious focus of the serum. It is part of the finished formulation rather than a drying powder or a separate spot treatment that must be mixed into each application.
- Acetyl glucosamine and allantoin: Acetyl glucosamine supports the tone and texture focus, while allantoin contributes soothing care. The blend helps balance a targeted cosmetic routine with a comfortable finish rather than a deliberately tight, stripped sensation.
- 20mL dropper bottle: Apply a few drops for an even layer between toner and cream. The light, non-sticky texture is suitable for layering, and the glass bottle can be separated from its cap and dropper components for appropriate local recycling.
A more balanced-looking complexion and smoother texture
This serum is intended to address several visible concerns that often accompany oily, blemish-prone skin. The practical goal is less obvious shine, a more refined-looking surface and a clearer-looking tone over time. It does not remove pores, guarantee that breakouts will stop or replace medical treatment for persistent acne.
- Less visible excess oil: Supports a more balanced-looking finish when unwanted shine is a concern. Continue moisturizing rather than trying to compensate for oiliness by leaving the skin dry and uncomfortable.
- Refined-looking pores: Helps improve the appearance of enlarged pores and uneven texture. Pores remain a normal part of skin; the aim is a smoother-looking surface, not their permanent removal.
- More even-looking tone: Regular use can help reduce the appearance of post-breakout marks and unevenness, especially as part of a consistent routine that includes daily broad-spectrum sunscreen.
- An uncomplicated serum step: The light texture fits beneath cream without demanding an elaborate layering routine. A measured amount lets you introduce the product gradually and assess whether it suits your skin.
