Melaleuca Alternifolia Leaf Oil

Tea Tree Oil is a pale yellow to colorless essential oil steam-distilled from the leaves of Melaleuca alternifolia, a tree native to Australia. It contains high concentrations of terpinen-4-ol (30-48%) and γ-terpinene, which give it potent antimicrobial properties against bacteria, fungi, and some viruses, making it particularly valued in acne treatments and scalp care products. Formulators choose it not only for its broad-spectrum antimicrobial activity but also for its fresh, medicinal-camphoraceous scent and ability to enhance skin penetration of other actives, though it must be used at controlled concentrations (typically 0.1-5%) due to potential skin sensitization at higher levels.
