Tea tree oil, also known as melaleuca oil or ti tree oil, is an essential oil with a fresh camphoraceous odor and a colour that ranges from pale yellow to nearly colourless and clear.

One of tea tree oil's benefits is as a home remedy for acne. A 5 percent solution of tea tree oil works just as well as the top drugstore acne remedy, benzoyl peroxide, according to Australian researchers studying their native resource. Dilute a few drops of tea tree oil with 20 to 40 drops of witch hazel, and apply to the skin once or twice a day with a cotton swab. Be careful to not overuse it: while gentler than benzoyl peroxide, tea tree oil can dry out your skin, triggering your body to overproduce its own oils and make your acne worse. If you apply it to your face, stay out of the sun.
