Tea tree oil remains a key player in the beauty sphere – find out why here 


In the realm of skincare, there are certain buzzy ingredients that always steal the spotlight (enter vitamin C, hyaluronic acid and retinol). Others, such as tea tree oil, are more under-the-radar ingredients, but no less popular.  


In fact, tea tree oil has been used in skincare for centuries and is one of the top-searched skincare ingredients in the UK

What is tea tree oil? 


‘Tea tree oil comes from the leaves of the tea tree (Melaleuca alternifolia), that grows in the swampy southeast Australian coast,’ says Dr Osman Bashir Tahir (aka Dr OBT), aesthetic doctor and founder of Halcyon Aesthetics.  


Now, this ingredient plays a starring role in several skincare products, from cleansers and toners to masks and overnight treatments. 


How to use tea tree oil 


Like most plant oils, tea tree oil is very potent in its 100% purest form and can actually trigger a sensitised reaction (think redness, dryness and peeling). ‘This is why you should never apply pure tea tree oil directly onto your skin,’ says Dr Tahir. 


Rather, it’s important to dilute tea tree oil first. ‘You can do this by adding it to a carrier oil like coconut, olive or almond,’ says Dr Tahir, which will reduce the product’s potency and make it suitable for skin. That said, ‘if you have very sensitive or eczema-prone skin, you should avoid tea tree oil entirely as it can cause irritation,’ adds Dr Tahir. 


For those looking to reap the benefits of tea tree oil, seek out products containing low concentrations that have been specifically formulated for skin. 


What are the benefits of tea tree oil?


There are several reported beauty benefits of tea tree oil. When applied topically, it’s thought to help reduce bacteria on the skin’s surface and with excess sebum. 


It could also help tackle scalp concerns. ‘Using a small amount of diluted tea tree oil on the scalp can help prevent product build-up and dead skin,’ says Dr Tahir. This is why tea tree oil shampoos often target dandruff.
