numbuzin has become one of my favorite brands along with cosrx. this is one of the two serums i own from them, this and the no.5 goodbye blemish serum.
i've only been using this since march of last year and it has been a game-changer ever since. i feel a bit dramatic when i say this, but i genuinely have seen a big difference in my skin using this compared to any other serum i've ever used. it Show more
I had small bumps everywhere and my skin is quite sensitive but this worked very well. It made my skin almost completely smooth. The only thing it didn't fix was the stubborn closed comedones on my jaw and chin which wont go away no matter what.
