Do clogged skin pores cause pimples?

When a pore becomes clogged with oil and dead skin cells, a blackhead or whitehead may result. If bacteria infect the clog, the skin can become red and inflamed, causing a pimple. Outbreaks of pimples may be triggered by hormonal changes that stimulate the oil-producing (sebaceous) skin glands. These changes can result from puberty, pregnancy, menstruation, and the use of birth control pills. External triggers include facial creams, makeup, greasy hair ointments, clothing that irritates the skin, and sweat. Even stress is known to trigger pimple outbreaks.
