Can have anti-inflammatory effects to calm irritated skin
Often used to address oily or congested skin
Potential concerns
Can cause irritation, redness, or sensitivity in some people, especially with undiluted use
May trigger allergic contact dermatitis in sensitive individuals

Science: Tea tree oil has been studied for antimicrobial activity against acne-causing bacteria and shows some efficacy in clinical trials, though results vary. It is generally recognized as safe in cosmetic formulations at typical use levels, but undiluted or highly concentrated forms carry higher irritation risk.
