I've bought 2 bottles of this before, and currently trying something else as the price tag is a bit high. I do love it, and everytime when I'm trying another niacinamide product, I compare it to this one. My skin will feel more behaved, as I'm prone to very oily skin, especially in the summer. I would recommend it!

This serum is one of the best products I ever used and I simply can’t live without it anymore! Okay, the smell is a turn off, but it fades very quickly, so it’s not really a problem. The blue serum has a light consistency and os almost instantly absorbed by the skin. My pores are better and my oily skin is no longer oily. It gives also a plump effect which is amazing and helped with some dark spots, since it leaves the skin more uniform. Do yourself a favor and try this.

I really liked this but it was a bit heavy and sticky to layer

I am really happy with this niacinimide. It is really gentle and didn't cause my skin to get irritated. I will definitely repurchase!

Cannot be compared with other products. If you haven't tried copper peptides - go for it. This is a complex serum which does make a difference.
