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.

    Amazing Formula

    I have been struggling with painful cystic acne for the past 5 years and finding the right products for my sensitive skin. I decided after a lot of research to revamp my entire beauty regim and WOW my skin is now clear and the scars are fading quickly. I use this serum 2x a day and I am quite pleased so far. I combine this with a good cleanser, retionoid serum, hydrochloric acid, lightweight moisturizer (and sunscreen during the day).

    Very high quality skincare

    Pure essence of skincare compounds. I noticed a difference in my skin immediately after using. COSRX is proving to be much more than just a snail goo company!

    I love this product. I

    [This review was collected as part of a promotion.] I love this product. I have struggled with large pores for so long, but this has helped shrink them so significantly. I also have pretty sensitive skin, but this doesn’t irritate my skin at all. My only complaint is that it doesn’t last as long as my other COSRX products, but it honestly feels worth it because it does so much for me.
