FunctionEssential Oil

What it is — Melaleuca Alternifolia (Tea Tree) Leaf Oil (INCI: Melaleuca Alternifolia (Tea Tree) Leaf Oil), also known as tea tree leaf oil, is an essential oil.

What it does — It is commonly used as tea tree essential oil, broadly antimicrobial and antifungal.

Typical use — It is used in small amounts, largely for its natural scent and aromatic character. Natural does not automatically mean non-irritating, which is why exposure is kept low.

Who it suits / good to know — Essential oils can contain naturally occurring allergens and may not suit very sensitive or fragrance-avoidant skin. Patch-test if you react to scented products. If you are pregnant or highly reactive, you may prefer fragrance-free options.

Safety — DHALIORA grades it mid risk: essential oil, known irritant/allergen at higher concentrations. This reflects the ingredient in general and is not medical advice; patch-test before wider use if your skin is reactive.

Why we grade it Mid: Mid risk — essential oil, known irritant/allergen at higher concentrations.
How grades are set — Risk reflects our own reading of publicly available safety data, an EWG-style reading shown at the worst-case grade we've assigned this ingredient across products. It isn't a third party's proprietary score, and it isn't medical advice. Always read the packaging and patch-test where indicated.
