Acne
What is this condition?
A person with acne experiences persistent, recurrent blemishes on the skin. Acne primarily affects adolescents, but lesions can appear as early as age 8. Although acne strikes boys more often and more severely, it usually occurs in girls at an earlier age and tends to last longer, sometimes into adulthood. The prognosis is good with treatment.
What causes it?

Research now centers on clogged skin follicles, production of an oily substance called sebum (stimulated by hormones called androgens), and a bacterium called Propionibacterium acnes as possible primary causes. Theories focusing on dietary influences appear to be groundless.
