I was in need of new toner as the one I originally used get new edition and that one made my face break out. And after my satisfaction with other Cosrx´s products I decided to try this one it did not dissapoint me. Not only it didn´t break me out it  also reduced the amount of pimples on  my forehead. Nice is also the fresh look and glowiness my face gets after using it. I use it only in the night and I usually do 4 really thin layers.
