Really feel the effects on my skin within a week using and other people have noticed the difference too! I'm super choosy when it comes to products because I have PCOS, but this one did not cause any side-effect on me :)
I've tried this before when i had free samples, and got the same product when i went to Korea. I've bought this here 2 times now and still one of my fave toners!
Is very nice for my skin
