Tea Tree Oil Acne Benefits: A Natural Treatment for Clear Skin

Originally posted February 2018 / Updated September 2023

What Is Tea Tree Oil?

Tea tree oil comes from the leaves of Melaleuca alternifolia, a small tree native to the northeast coast of New South Wales, Australia. Due to its unique properties, tea tree oil is beneficial as a topical treatment in fighting acne.

Tea Tree Oil Acne Benefits

The development of acne is linked to an overgrowth of a bacteria, Cutibacterium acnes, that lives deep within follicles and pores in the face. C. acnes feeds primarily on fatty acids in sebum secreted by sebaceous glands in the follicles. Factors that increase sebum production, such as the increase in hormones with puberty or blockage of the pore or follicle, can lead to the C. acnes bacteria to multiply and overgrow.

Tea tree oil possesses significant antimicrobial properties due to terpene compounds. The antimicrobial action, coupled with tea tree oil's ability to penetrate the deepest levels of the skin and within skin pores and follicles, makes it particularly helpful in acne. The tea tree oil terpenes kill off the C. acnes bacteria and help soothe inflamed and irritated skin.

Research on Tea Tree Oil

A study evaluated tea tree oil's mechanisms, efficacy, and safety as an acne treatment. Five studies utilized commercial products providing 5% tea tree oil as a gel or face wash. The research showed that tea tree oil applied twice daily reduced the number of acne skin lesions from 23.7% to 62.1% after products were used for 4 to 8 weeks. 

These results are similar to those found with benzoyl peroxide. Researchers have also found that tea tree oil is much better tolerated than benzoyl peroxide and other conventional topical treatments.

While many over-the-counter creams, gels, and face washes are available that contain tea tree oil, consider a do-it-yourself cream. The added benefits of making a wash at home include creating higher concentrations of tea tree oil preparations without added chemicals or fragrances.
