Years ago antibiotics were used to treat acne because it was thought that the condition was an infectious disease, says Dr. Hilary Baldwin of the Rutgers Robert Wood Johnson Medical School in New Jersey. However, it is now realized that while Propionibacterium (P) acnes is implicated in the pathophysiology of the condition by producing an inflammatory cascade, acne is not the result of a bacterial infection because all adults have P. acnes in follicles and the severity of acne does not correlate with P. acnes counts.
