I've been using this toner for about a week, so not a full 30 days yet but so far I'm satisfied.

Before this one I used the AHA and BHA toners from COSRX, so I already knew my skin reacts well to them. Either way this toner seems to work just as well.

Didn't break me out, and I love the smell and feel of it.

It smells very minty to me, and gives a cool, refreshing sensation on the skin.

Hoping to see more improvement with continued use, will probably repurchase.
