Meh
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.

so good!
this was my first time trying out this product and I was pleasantly surprised. I currently don't have excessive breakouts to deal with because I have been on medication to treat cystic acne BUT I still have to deal with large pores and blackheads. I have found that this serum made my skin feel hydrated while keeping sebum production to a minimum. it made my skin feel less oily in my T zone which is my usual problem area. I felt like this serum helped balance out the moisture in my skin and made my last skin care step work better than before. I am currently not pairing this serum with any other cosrx products but the ones I have used from Pyunkang, Neogen, TheLab and Rovectin has paired well with this serum. I am definitely going to repurchase again but I wish it was offered in a slightly larger size because this bottle is really small. I wish it was at 30-40ml instead of 20ml.

Awesome serum
It is one of my favourite serum from COSRX. It definitely works, i see results. My skin looks fresh and younger. Use it morning skin care routine.

For oily skin - THIS IS IT!
It has a thinner consistency compared to other potent Niacinamide serums. Also more hydrating, not stripping. It really does help with oil control throughout the day! I wear makeup daily & mornings are hot! I have actually SEEN a difference when I use this as my skincare base in the AM! Sebum is controlled while not feeling dry & consistently using has visibly helped skin texture! Combo with Acetyl Glucosamine!

Great!
This serum comes in a 20 ml black glass bottle, the same design of the hyaluronic acid serum. I was a bit scared with this one because contains 15% of niacinamide, this is the highest porcentaje I’ve used but I didn’t experience any irritation or breakouts while using this. This also contains Acetyl Glucosamine that has anti-wrinkles and anti-pigmentation properties and Zinc that helps with the sebum production. The consistency is viscous, absorbs fast and is slightly sticky but after some minutes the sticky feeling disappears, it also gives a beautiful glowy finish. My skin is GLOWING everytime I use this and I honestly love it, overall this is my favorite out of the three.
