Melaleuca Alternifolia (Tea Tree) Leaf Oil

Melaleuca alternifolia leaf oil, also known as tea tree oil, is one of the most well-known ingredients in skincare and is praised for its antiseptic and antimicrobial properties.

It is an essential oil distilled from the leaves of the Tea tree, Melaleuca alternifolia, or several other related species of Melaleuca. It is native to Australia and has been used by Aboriginal Australians for centuries.

It is characterized by the high content of terpineol and terpinene, with cineol comprising max. 10-15%. These compounds are all pleasant-smelling, volatile components of the essential oil and they give it the fresh, camphor-like smell, as well as mild antioxidant and anti-inflammatory properties.

The activities of Tea tree essential oil and its components have been widely researched, although unfortunately mostly in vitro (in test tubes and cell cultures). The clinical studies on the efficacy are rare.

Nevertheless, it is widely used in skincare products for its antimicrobial properties and can help to treat acne, inflamed skin, and small wounds.

Like all essential oils, however, it should never be used undiluted directly on the skin. It might cause allergies and skin irritations. It is also not recommended for children under 12 years old.
