Acne is a skin condition characterized by whiteheads, blackheads and inflamed red pimples or "zits."
Acne occurs when tiny holes on the surface of the skin called pores become clogged. Each pore is an opening to a canal called a follicle, which contains a hair and an oil gland. Normally, the oil glands help keep the skin lubricated and help remove old skin cells. When glands produce too much oil, the pores can become blocked, accumulating dirt, debris and bacteria. The blockage is called a plug.
