Composition of Thyme Essential Oil
The composition of thyme essential oil varies greatly depending on the species of Thymus and the environmental conditions where it was grown. In many cases, the most abundant compound in thyme essential oil is thymol, which can account for up to 50% of the total volume. However, some samples of thyme oil may have high levels of other compounds, such as camphor and caravacol, and relatively low levels of thymol.
In addition, thyme oil usually contains a large number of compounds in trace amounts. Many of these compounds are also found in other aromatic essential oils that have antibacterial properties, such as tea tree and clove essential oil.

Thyme Essential Oil in Acne Treatment
Thyme essential oil is toxic to a range of bacteria and fungi, including Propionibacterium acnes. Laboratory tests indicate that thyme oil is one of the most effective essential oils at inhibiting bacterial growth.
However, there is limited evidence that thyme oil is an effective treatment for acne. In pure form, thyme oil is a potent irritant of the skin and mucosal tissue. Thyme oil must be diluted below 5% and below prior to topical use.
Thyme oil can be blended into an alcohol or carrier oil base to make customized solutions. Small amounts of thyme oil may also be added to hot water and applied as a warm compress.
