If you have oily skin this is a great toner. It didn't feel moisturizing enough for me, so I just use it on summer days. I won't be repurchasing but just for that exact reason, otherwise it's a great product.
Absorbs somewhat quickly into the skin, leaving a refreshing sensation. Has no smell.

It didn't do anything to my skin, not sure what differentiates it from regular water... it doesn't even spread very well. It leaves a bit of a nice cool wet feeling and that's about it, so if you want centella or a nice toner probably just buy something else that's actually worth your money

One of my favorite toners ever (if not theee favorite among all)! It's really lightweight and watery, but it's amazing how hydrating it is. I also think it helps to soothe irritated skin.
