Acne is a red, irritating skin rash primarily affecting teenagers and young adults. It can, however, occur at all ages.
Typical acne appears in the oil-producing areas of the body namely, the face, chest, and back.
Acne can also occur on the neck and upper arms. Acne can have a short-term, potentially lasting psychological effect. Left untreated, severe acne can lead to disfiguring scarring, which can itself be difficult to treat. Several myths exist about acne. Acne is not a result of uncleanliness or infrequent washing.
