Acne is the term for the pimples and complexion problems that trouble many young people.  Pimples occur mainly on the face, but often involve the neck, chest, back, and upper arms.  It is usually caused by the oil glands of the skin becoming plugged and breaking open.  At puberty, the oil glands in the skin start producing an oily material called sebum. Acne can be controlled with using an number of treatment options.

Treatement, however, depends on the severity of the acne.  Mild acne usually responds well to medicines applied to the skin (topical treatments) and moderate acne usually requires antibiotics taken orally (e.g., tetracycline, erythromycin, and minocycline are among the internal antibiotics used in treating acne).  Server acne is best treated with isotretinoin.
