Description
The Niacinamide 15 Serum with Acetyl Glucosamine + Zinc PCA from COSRX is a highly concentrated serum that combines the maximum concentration of niacinamide with optimal ratios of synergistic ingredients for total acne control.
Key Ingredients:
Niacinamide : Provides total acne care by controlling sebum production, soothing acne inflammation and diminishing post acne scars
N-Acetylglucosamine (NAG) : Works in synergy with niacinamide to effectively fade hyperpigmentation
Zinc PCA : Inhibits inflammation and promotes recovery of damaged skin
Allantoin : Promotes collagen synthesis to facilitate skin regeneration
How to use:
After cleansing, during the serum phase, apply a few drops to the skin. Use fingertips to gently massage and absorb the serum, starting from the center of the face working towards the edges. Highly concentrated serums should only be used in the evening? NO! This serum can be used in the morning and/or night. If applied in the morning, be sure to use with a SPF of 30 or higher
All COSRX products are dermatologist-tested, hypoallergenic, paraben-free, sulfate-free, phthalate-free, and alcohol-free.

Oil Slick ➡️ Matte-tastic!
Used this before bed last night and woke up to a matte face! I'm in my 40s and there hasn't been a day since puberty that I didnt wake up looking like an oil slick… until now! Hoping it helps my sebaceous hyperplasia too! That's what another review mentioned, which was why I bought it. 🤞🏼Excessively oily girlies - this is your solution!

Incredible for oily skin under makeup
Oily skinned folks - use this!!! The difference is notable. Use at night and again in the am under makeup and the difference is huge. I’m usually an oily mess by lunch but everything looks so good by the end of the day.

My second bottle of COSRX
[This review was collected as part of a promotion.] My second bottle of COSRX Niacinamide 15 and I will continue to purchase. I have tried many other Niacinamide Serums and it beats all the others hands down for quality and price. You can see pore reduction quickly and my sun spots have decreased with time. I do not have sensitive skin, I use it in the AM after CORSRX C Serum and my skin tolerates it very easily. Give it a shot

[This review was collected as part of a promotion.] This serum has really helped brighten my skin and smooth out the texture! I'm on my second bottle. If I use it twice a day I can feel a little bit of a burning sensation, but it's good if I only apply it once a day.

I love this Niacinamide 15
[This review was collected as part of a promotion.] I love this Niacinamide 15 serum. It is one of the best Niacinamide products I have tried and also very reasonably priced for its effectiveness. It is one of the only serums that I can see noticeable brightness and a little improvement in fine lines the day after I use it. I will continue to use this serum regularly.
