Bergamot Essential Oil is purported to help improve acne symptoms and skin tone when used topically. Unfortunately, there is virtually no clinical research into the use of Bergamot Essential Oil as an acne treatment. Laboratory testing indicates that Bergamot Essential Oil is mildly toxic to some types of gram-positive bacteria, such as the acne-causing P. acnes bacterium. However, these laboratory test results found that many other types of essential oil (eg. Rosemary) had significantly more antibacterial activity than Bergamot Essential Oil.
