Acne often appears in young earned him international notoriety, and he was offered a posi- women at the time of their monthly menstrual period. The most severe form, called cystic acne, may produce marked inflammation over the entire upper body, and requires a physician’s attention to reduce the bacterial populations. Reduction in the bacterial number involves slowing down the secretion of the oil from the oil glands and making the follicle pore more open, so that the normal outward flow can occur. Oil production can be slowed in the presence of 12- cis-retinoic acid (Accutane). Use of this medication is reserved for severe cases of acne, as the retinoic acid can have significant adverse side effects. For example, many antibacterial creams and face washes contain the compound called benzoyl peroxide, which is very active against Proprionibacterium acnes. Because the bacteria active in acne are normal residents of the skin, there is no “cure” for acne. Rather, the condition is lessened until biochemical or lifestyle changes in the individ- Facial acne caused by Propionibacterium acne.
