Description

Key Benefits:

  • Regulates Sebum Production: Niacinamide is renowned for its ability to balance natural oils, keeping your skin neither too dry nor too oily. This regulation is crucial for preventing future breakouts and maintaining a clear, matte complexion.
  • Smooths and Refines Skin Texture: Say goodbye to rough, uneven skin. Regular use of this serum smooths out skin texture, leaving you with a surface that’s soft to the touch.
  • Fades Scars and Hyperpigmentation: This formula incorporates N-acetylglucosamine (NAG) to not only tackle existing acne but also reduce the appearance of acne scars and dark spots, offering a brighter and more even skin tone.
  • Maintains Oil-Water Balance: With zinc PCA, this serum maintains the perfect harmony of moisture in your skin, preventing the dehydration that can often be mistaken for dryness in acne-prone skin.
  • Boosts Collagen Production: Allantoin isn’t just a soothing ingredient; it also encourages collagen production, promoting skin’s elasticity and reducing the appearance of fine lines.

CosRX The Niacinamide 15 Serum is not just a skincare product; it's a powerful ally for anyone struggling with the daily woes of acne-prone skin. Expertly formulated with an impressive 15% concentration of niacinamide, this serum is ready to take on the most stubborn skin issues and transform your complexion.

Lovely serum

Great serum if you need a Niacinamide boost in your skin care. No fillers, no frills just a nice dose of Niacinamide. It reduces acne scars which we could use
I do like the fact that it comes in a bigger bottle. This serum is also good for reducing hyperpigmentation and dark spots which is literally what is good for. Highly reccomend.

Can’t live without this!

I always have to have a niacinimide in my skincare routine and this one is definitely top tier. I have a super oily T zone and large pores and I feel like this product helps me keep them under control. I also love that this soaks into the skin nicely, has no scent, and isn’t harsh at all!
