COSRX The Niacinamide 15 Serum, 0.67 oz.

[This review was collected as part of a promotion.] Wow! A co-worker shared your products with me. I have scaring around my eyes and face due to terrible allergy symptoms. I have always taken care of my skin and took pride and how I looked. This was devastating for me to have scars on my face. I received your product and have been using it for a week and all I can say is how I cried because this helped me so much. I have seen the difference in my skin and I can’t say thank you enough.

Absorbs into my skin nicely. Has completely helped with random breakouts and evening my skin.

[This review was collected as part of a promotion.] I chose this serum because of its high quality ingredients and Cosrx's strong reputation The formula feels lightweight and absorbs easily. Since I have only recently started using it I would like to continue for at least a month to fully evaluate its long term results. So far my experience has been very positive.
