Melaleuca Alternifolia (Tea Tree) Leaf Water (009%)

Melaleuca Alternifolia Leaf Oil, commonly known as Tea Tree Oil (TTO), is an essential oil distilled from the leaves of the tea tree (Melaleuca alternifolia, Myrtaceae), native to Australia. It is a complex chemical mixture of approximately 100 components, with the major ones being terpinen-4-ol (~40%), γ-Terpinene (~23%), and α-Terpinene (~10%). Terpinen-4-ol is considered the primary active component, though most constituents contribute to the oil's overall activity. It has been used for nearly 100 years for its antiseptic and anti-inflammatory properties.

● Benefits

Tea tree oil is a well-established anti-acne ingredient, with multiple studies confirming its effectiveness against P. acnes; a 5% TTO gel has been shown to be comparable in efficacy to 5% Benzoyl Peroxide lotion, though with slower onset and fewer side effects. It also exhibits strong antibacterial, antiviral, and antifungal effects. Its allergen content is minimal compared to many other essential oils, though irritant and allergic reactions can still occur, particularly from oxidation products in older or improperly stored oil.
