Why is Tea Tree Oil used in Skincare?

Tea tree oil is one of the most popular natural ingredients in skincare. It can be found in a range of products targeting acne, oiliness, and even scalp care products for dandruff or itchiness. Today, we’ll take a closer look at the skincare health claims associated with tea tree oil and learn more about why it has remained a staple in the industry for decades.

Tea Tree Oil Background

Tea tree oil comes from -- as the name suggests -- the tea tree plant’s leaves. This plant is found primarily in southern Australia, where its medicinal benefits have been reaped for centuries. In skincare, it has been incorporated into cleansers, toners, clarifying masks, and overnight deep treatments.

It is important to note that tea tree oil in its purest form is much too strong to use on the skin without causing irritation or more severe reactions. Tea tree oil must be diluted or balanced with carrier oils and other ingredients before it can be safely used on the skin. For this reason, it is recommended to seek products with low concentrations and to begin introducing the ingredient slowly while watching for signs of excess sensitivity.

Tea Tree Oil Skincare Benefits


Tea tree oil is a natural astringent, meaning it reduces excess oil, tightens your skin, and reduces the appearance of your pores. When used as a toner and balanced appropriately with other ingredients to avoid irritation, it can be a great option for giving your complexion a smoother and more even look.


Tea tree oil is most commonly known for its uses in acne treatment because the powerhouse ingredient is believed to be naturally antibacterial. This plus its astringent properties deter excess bacteria and sebum from building up on the surface of the skin and can prevent breakouts. Further, it can help to reduce the extent of swelling on larger breakouts such as those associated with hormonal, cystic acne.

Scalp Care

There are a variety of benefits to using tea tree oil in your hair care routine, namely the clarifying effects it has on your scalp. The oil maintains its astringency when applied to your scalp in small doses, making it a great tool for addressing oily roots, dandruff, and even product build-up.

Tea Tree Oil FAQs:

Is Tea Tree oil safe?

Tea Tree oil can be used safely when it is properly diluted, for example by mixing it with a carrier oil or using it in a product with a lower concentration of the oil.

Is Tea Tree oil good for oily skin?

Tea Tree oil is a great choice as a toner or cleanser for those with oily-prone skin, as its astringent properties work to reduce excess sebum accumulation on the skin and can aid in creating a more matte appearance.

Is Tea Tree oil good for Eczema?

It is not recommended for people with eczema or other sensitive inflammatory skin conditions to use tea tree oil, as it may be too drying or cause additional irritation. Those with eczema should opt for products with gentler ingredients, such as jojoba oil.
