Tea tree oil contains a compound called terpinen-4-ol that fights bacteria, fungi, viruses, and inflammation on skin. Research suggests it may help with acne, dandruff, gingivitis, wound healing, and possibly even skin cancer—though this review doesn't specify how effective it is compared to other treatments or at what concentrations.

This is a literature review, meaning the authors summarized existing research on tea tree oil rather than conducting their own experiment. They looked at multiple studies about how dermatologists have used it.
