Tea tree oil is an essential oil derived from the leaves of the Australian tea tree (Melaleuca alternifolia). Although no scientific research has been done on the use of tea tree oil for skin tags, anecdotal reports suggest that it works. People claim that tea tree oil dehydrates skin tags, causing them to dry up and fall off.

Skin tags are painless, flesh-colored growths that hang off the skin. They’re very common, affecting up to half the population. Skin tags are harmless, but they can be unsightly and uncomfortable when they grow in delicate locations such as the eyelids, groin, and armpits.
