Study 1:
In a clinical trial, a diluted tea tree oil gel and benzoyl peroxide lotion were both evaluated for mild to moderate facial acne. The research observed reductions in acne lesion counts with tea tree oil, along with lower reports of dryness and irritation compared with benzoyl peroxide.
Study 2:
A human pilot study evaluated facial products containing tea tree essential oil used twice daily over 12 weeks in individuals with mild to moderate acne. The research observed reductions in acne lesion counts and in skin oiliness over time.
Study 3:
A scientific review evaluated human research on tea tree oil and acne, noting changes in inflammatory lesion counts associated with topical tea tree oil use. It also described tea tree oil’s antibacterial and anti‑inflammatory properties.
Study 4:
In laboratory tests, terpinen‑4‑ol was associated with antibacterial, antifungal, and antibiofilm activity against Staphylococcus aureus cultures, with concentrations inhibiting bacterial growth and formation of biofilms.
Study 5:
A laboratory study investigated tea tree essential oil and its components against an influenza A (H1N1) virus strain in cell cultures. The research observed that the essential oil and some of its constituents reduced influenza virus replication in this controlled laboratory model.
Study 6:
A laboratory study explored how tea tree oil impacts influenza A virus infection in cell cultures. The research observed that exposure to the oil, shortly after viral infection, was associated with reduced viral replication, indicating an effect on early steps of the viral cycle.
