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

    I am thrilled with this

    [This review was collected as part of a promotion.] I am thrilled with this Niacinimide serum and can’t believe how quickly it has benefited my skin. After just a couple of applications I noticed that my skin was clearer and smoother. It is perfect for my combination skin. I have tried several other products to improve my complexion but none have had the positive impact as this serum. I highly recommend it.

    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).
