Tea tree leaf water is the aqueous fraction obtained during distillation of Melaleuca alternifolia, containing low concentrations of tea tree oil constituents. It is used in skincare for mild antimicrobial, astringent, and soothing properties, often as part of the water phase in formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Uncommon | Mild stinging or redness possible, especially on sensitive or compromised skin. |
| Allergic contact dermatitis | Uncommon | Tea tree components, particularly oxidized terpenes, are recognized sensitizers. |
| Dryness | Rare | Astringent effect may contribute to dryness in some users. |
| Systemic toxicity if ingested | Very rare | Relevant to concentrated oil; aqueous fractions are far lower in active terpenes. |
