Acne - What Happens
Acne develops most often in the teen and young adult years. During this time, both males and females usually produce more testosterone than at any other time in life. This hormone causes oil glands to produce more oil (sebum). The extra oil can clog pores and cause acne. Bacteria can grow in this mixture. And if the mixture leaks into nearby tissues, it causes swelling, redness, and pus (pimples).
Acne usually gets better in the adult years when your body produces less testosterone. Still, some women have premenstrual acne flare-ups well into adulthood.
Most people develop acne -- the most common skin condition -- to some degree, but it primarily affects teenagers undergoing hormonal changes. Acne may be mild (few, occasional pimples), moderate (inflammatory papules), or severe (nodules and cysts). Treatment depends on the severity of the condition.
