What it is
A natural extract derived from the flowers and leaves of Melaleuca leucadendron viridiflora, a tree native to Australia and Southeast Asia. It contains compounds like terpenes and flavonoids that give it antioxidant and antimicrobial properties.
How it works
When applied to the skin, the extract's compounds may help reduce surface bacteria and calm redness. It also provides antioxidant protection against environmental stressors, helping to keep skin balanced and comfortable.
Pros

Unlike stronger tea tree oil, this extract is less likely to cause dryness or irritation, making it suitable for daily use on sensitive or reactive skin.
Antioxidant support
The flavonoids in the extract help neutralize free radicals from pollution and UV exposure, supporting overall skin health and resilience.
Cons and cautions
Limited research
Most evidence for niaouli extract comes from traditional use and lab studies, not large human trials. Its benefits are promising but not as well-documented as some other botanicals.

Best for
