What can you tell me about Tea Tree Oil and Witch Hazel for the skin?
I work in a Cosmetic Clinic and we use and recommend Witch Hazel for acne and have found good results. Tee Tree oil is a wonderful product but you need to be very careful as it can burn. If you put it on a blemish, use a cotton tip.

Reply:Teatree oil is a good antiseptic. After a pimple pops, it has a wound and that wound exposed to bacteria turns into a dark spot. If you put teatree, although it gives a slight sting on an open wound, it keeps the wound cleaner than usual. So the spots are not as dark. In some cases the spot completely heals and there is no mark. I used Body Shop's teatree oil. It's ok for me.
