Pretty good toner - It's very light and refreshing. Hasn't broken me out. I think it works very well with the Cosrx AHA/BHA products. What I really like about this toner in particular is that you can just spray it on! Very convenient and easy to use - no fuss! The reason I'm not giving it 5 stars is just because I haven't come across a toner that has done miracles for my skin. I will say thought that once you spray it on, and let it sit for while, it does sort of look like it makes your skin LOOK smoother lol. It might just be cheating my eyes though =D I like it so far... once I finish the bottle, I'll see if I should repurchase it or not.
