Answer:
If you have acne you are trying to get rid of - you need tea tree oil. It works on your neck, face, back, legs, everywhere! It will make a huge difference overnight. But be careful, stick you 2x a day (after you wash your face in the morning and after you wash at night) otherwise you will get wicked peeling. Putting it on more often does not help, it makes it worse.
Also, you may feel your skin to be dry or burning. Just wait 5 minutes (or until it dries) and then put on some tea tree oil ointment (purest ingredients only! Like jojoba oil, beeswax, lavender oil, etc) or clean&clear dual action lotion. If it really burns, wash it off immediately with cool water and put on moisturizer!
The best stuff you get it 100% but if you find your skin is to sensitive, try just the ointment or a lesser percentage of oil.
My daily routine is I wash my face in the morning with burt's bees acne scrub then put on dabs of tea tree oil where needed. Then I put on clean and clear dual action moisturizer or tea tree oil ointment. Then at night I put raw, unpasteurized honey on my face (you can find it at health food stores. IT HAS TO BE RAW PURE HONEY TO BE AFFECTIVE) a few minutes before I jump in the shower. Then I leave it on a few minutes after I'm in the shower so the steam opens my pores and the honey can be more effective. Then after I get out I dab on some more tea tree and moisturizer.
