Acne is a skin condition that occurs when hair follicles or pores become clogged with oil and dead skin cells. It is the most common skin condition in the United States. Acne is characterized by red bumps, blackheads, and pimples. Although it can develop anywhere on the body, acne is most commonly found on the face, back, and chest. In some cases, acne can become infected with white pus and may be a sign of a more serious health complication.
