Star2 qty Cosrx The Niacinamide 15 Serum:
Sen...@ Product Claim: Cares all about acne & Effectively controls excess sebum and tightens Pores Main Ingredient: Niacinamide 15% My experience: I am very nervous and surprised that this serum contains 15% of Niacinamideand to be honest I am very afraid to use it at first because my skin is not in good condition. But for sure i am still trying it on my skin and it kinda Dries out my skin and i don’t like this serum at all. I think this serum is more for oily skin not the dry skin type like me.

Star3 qty Doesn't Control Oil for Me
unb...@ I had really hoped this would control my oily t-zone, but sadly it doesn't. I also REALLY dislike the way it smells. It smells like nail polish, nail polish remover or something like that. I still love COSRX, but this product isn't for me.

Star5 qty Great!
hel...@ I’ve used this serum every other day for about a month, and noticed a dramatic reduction in the pores on my nose as well as less breakouts. I’ll likely be purchasing this when I run out!

Star4 qty Meh
03....@ It gives a slight tingling feeling, not harsh or painful on the skin but I don’t know if this is normal. If anyone has tried this serum, has it been the same for you? It's lightweight, non tacky, and absorbs quickly though I think I prefer my 10% level of niacinamide. Once I’m ready to increase the concentration level, I would go back to this.
