Acne is a common skin condition that occurs when the sebaceous glands, which normally excrete oil to the skin’s surface, become clogged. The resulting red bumps are what we identify as pimples. 

Other types of acne lesions known as comedones appear—they are either blackheads (open comedones) or whiteheads (closed comedones). Occasionally, acne presents as large, painful bumps (cysts) below the skin's surface.

The severity of acne can vary from person to person. The condition usually dissipates over time, but it can persist, affecting a person’s social life or becoming so severe that it causes scarring.

“Acne is very common in the teenage population, but what many people do not realize is that it can persist into adulthood and throughout adult life,” says Ilya Lim, MD, a Yale Medicine dermatologist. “There is data that acne can have significant negative impact on the quality of life and even increase the risk of depression.”

At Yale Medicine, our doctors create a personalized approach to treating acne that takes into account how the condition is affecting the patient socially and emotionally.
