Tea tree oil, also known as melaleuca oil, is an essential oil with a fresh camphoraceous odor and a colour that ranges from pale yellow to nearly colourless and clear. It is derived from the leaves of the tea tree, Melaleuca alternifolia, native to southeast Queensland and the northeast coast of New South Wales, Australia. The oil comprises many constituent chemicals and its composition changes if it is exposed to air and oxidizes.
Tea tree oil is a popular choice for treating acne because of its anti-inflammatory and antimicrobial properties. It’s thought to calm redness, swelling, and inflammation. It may even help to prevent and reduce acne scars, leaving you with smooth, clear skin.
