The details

This ingredient is also known as tea tree leaf water or tea tree hydrosol. It functions as an antimicrobial, anti-sebum, astringent, and tonic ingredient. You can think of it as a gentler, water-version of tea tree oil . Its star active is terpinen-4-ol , a broad-spectrum antimicrobial. The water-soluble compounds of tea tree have been shown to calm inflammation by roughly 50% in vitro (with Terpinen-4-ol driving this). Terpinen-4-ol has also demonstrated strong inhibitory activity against Propionibacterium acnes and Staphylococcus aureus. Before slathering on tea tree water, just know concentrations under 5% are considered more suitable and safer than higher concentrations. The European Medicines Agency recognizes tea tree-derived ingredients as having well-established use for mild acne and small superficial wounds. It's a well-researched and skin-friendly option for oily or acne-prone skin. As with most actives, patch testing is a good idea if your skin leans sensitive.
