I can't honestly say that it ever improved my acne. I guess it depends on what's causing your acne. I'm one of those people who loves the smell of tea tree oil for some reason, and I believe its benefits to the skin when I read them on paper -- it makes sense. I mix a few drops of this into the hemp oil that I use on my skin as an overnight moisturizer because I think it helps to counter the oiliness of the... oil. Tea Tree Oil is one of those things that I've used on and off for about 10 years, but only as a supplement to something else. It's a decent supplement, but on its own it's not capable of a whole lot. In my experience. It never harmed my skin at all so I can't say it's not worth trying.
