What Is Acne?

Acne is a skin condition that can appear in the form of whiteheads, blackheads, and pimples. It usually develops during adolescence and may continue into adulthood due to hormones that increase oil production. The overproduction of this oil (sebum) can trap bacteria in the glands and cause acne. Because of this, acne tends to affect areas with a high number of oil glands, such as the face, upper chest, and back.
