As aromatherapy, it has such a clean, calming scent. But the best use I get out of this tea tree oil is for treating blemishes. I dab a bit right on the spot with a cotton swab, and it helps reduce the size of the pimple --often overnight.
Tea tree oil is known for its antibacterial properties, but in this form, it could also be too potent for the skin. Make sure to first test that the 100% pure oil is not too irritating for your skin, but if it is (and it probably will be) then you can just use it diluted.
