Tea tree oil, otherwise known as - Melaleuca alternofolia, is native to New South Wales in Australia, the leaves of this amazing plant have been used by Aboriginal peoples for thousands of years.
It's well known for it's anti bacterial properties, and is excellent for treating skin infections, especially viral conditions such as cold sores. Tea tree oil is also very good for treating acne outbreaks.
- So is tea tree oil any good for treating a condition like hyperpigmentation?
Although it's power is undeniable, as a treatment for dark skin spots, I would say no.
Hyperpigmentation is a condition where the skin produces too much melanin, and as more of an antiseptic treatment, tea tree oil would have little or no effect on this process.
There are many more natural hyperpigmentation remedies far better suited to lightening pigmentation, and one or more of these remedies will give the results you are looking for.
