Tea tree oil, otherwise known as melaleuca oil, is an essential oil distilled from an Australian plant called Melaleuca alternifolia, says Gretchen Frieling, MD, a triple board-certified dermatopathologist in Boston. It's a popular essential oil, particularly for its many purported skin benefits. It's also a relatively inexpensive product, with the cheapest bottles around $5.
But does it really work? Tea tree oil is an organic, healthy, and harmless ingredient that helps to keep the hair, skin, and nails healthy, says Frieling. How? The oil is proven to have anti-inflammatory, antiviral, antifungal, and antibacterial properties.
It’s important to note, though, that tea tree oil should not be applied directly to the skin, explains Frieling. Doing so can cause inflammation, irritation, and burning, adds celebrity facialist Candace Marino.
Before using, dilute it with other lotions or oils, which are typically called carrier oils, like olive oil, coconut oil, almond oil, moisturizer, and sunscreen. A good rule of thumb is 12 drops of carrier oil for every one to two drops of tea tree oil, Frieling recommends.
