I have only been using Tee Tree Oil for a short amount of time (7-8 days), but I am happy so far with the small progress I've made. I use Thursday's Plantation brand. Another person posted great results with this brand as well. Hope this helps.
I guess using anything with the word "oil" in it on acne makes me nervous. I recently bought some tea tree oil, but I haven't tried it yet. Testament, do you use it all over your face like an astringent, or just on pimples?
I 've had excellent results using Aura Cacia Tea Tree Oil 100% pure. Right now i had to settle for a some stuff i bought at walmart (the place i usually buy it at was out of stock)
I'm using Spring Valley 100%pure now and it seems to be doing its job (but i still perfer my usual brand )
