Tea tree oil is a potent essential oil steam-distilled from the leaves of Melaleuca alternifolia, a plant native to Australia. For generations, traditional native remedies relied on these leaves to soothe minor skin discomforts. Today, tea tree oil is widely recognized in modern cosmetic and topical formulations for its clarifying, cleansing, and purifying properties.
People frequently use tea tree oil to target skin blemishes, manage mild acne, clear up scalp flakes, and maintain healthy nails. Its natural cleansing properties make it a popular addition to serums, shampoos, and localized spot treatments. However, because it is extremely concentrated, it requires proper dilution to prevent skin irritation. Crucially, tea tree oil should never be ingested. If you are new to topical essential oils or manage sensitive skin conditions, consult a healthcare professional or dermatologist before incorporating tea tree oil into your routine.
