This is my first time using tea tree oil. I was in desperate need of a product to maintain my acne. I've used countless products and spent loads of money on special gadgets to improve my skin. I began researching after a bad breakout and came across many positive reviews for tea tree oil. Figuring I had nothing to lose I gave it a try and fell in love after first use. It's an incredible toner. Interestingly, it's an oil that strips oil away and leaves pores tight and clean. The smell can be a little strong at first, but I've gotten used to it. It is wise to dilute the oil with a moist cotton pad before applying to the face. Also be careful not to let it seep into your eyes. Frequently I experience some stinging in my eyes for a few minutes after applying. I apply before bed and when I wake up the blemish is well on its way to healing if I have popped it, which I admit to doing. Not good. Not to sound gross, but it also helps blemishes come to a head quickly, bringing that white icky stuff to the surface, but i find it to heal faster that way. Tea tree oil can be drying, so even though I have oily skin, if I apply it in the morning I follow it with jojoba oil mixed with a light oil-free moisturizer. This helps avoid flakiness under makeup. I hope it works for everyone suffering from problem skin!
