I have used this toner for a month now and have noticed both good and bad changes in my skin. Good thing is that my acne scars have faded quite alot while using this toner, but the negative thing is that more small pimples have popped up instead. I don't think it's a great toner if you have sensitive skin since I got red and irritated skin when i first started using it, but it might still be worth a try since not everyone reacts the same way. 

All in all I'd recommend this toner to people that have oily or combination skin, and if you have sensitive and dry skin maybe you should look for other options.
