Like its name it really does work WONDERS. I've been using this for a week and already all my blackheads have begun to surface and making it easy to get rid of them using a pore pack or by exfoliation. At first I was doubtful because surely a simple toner/freshener can't be THAT good if it's so simple and affordable especially when it has literally NO smell of alcohol and does NOT cause any stinging sensations on my face but OMG. It really is that good! Seriously this is my very first Korean skincare product I've ever bought and I'm a huge fan now. I think I might just buy a few more bottles to keep around in case of an apocalypse (and because I CANNOT live without it :D).
