I've been using this toner for a little over 3 weeks now, there hasnt been a huge change in my skin aside from a couple of small break outs that I dont believe are from this toner. But I do want to say that this toner isn't doing much for me. I have oily and acne prone skin and there wasnt a change in how much i broke out within the 3 weeks. The Toner has an alcohol scent to it along with tea tree (which is for the acne), its light, watery, and dries pretty quickly on the skin (most likely due to the alcohol in it). It isn't very hydrating (as expected) so I do have to follow up with a more hydrating toner before putting on the rest of my skin care. The toner didn't irritate or sensitize my skin over the period i've been using it. It just didn't do much. Overall, I wouldnt purchase again only because I like other toners better.
