Acne is a condition that occurs when the oil glands within the skin open, emitting sebum along the surface. The result is a pimple. When multiple oil glands open, multiple pimples may break out along the skin, giving the face or other skin surfaces a reddened, bumpy appearance.
Acne is most common in the teenage years and usually gets better during adulthood. However, it is not unusual for acne to continue to plague adults in their twenties, thirties, and older. At any age, acne can be embarrassing and may affect self-esteem.
Because acne may be caused by a number of factors, including diet, hygienic habits, the menstrual cycle, and stress, it is important to seek dermatological treatment to learn how to better manage acne and treat outbreaks.
