Acne is a red, irritating skin rash that is almost universal among individuals going through puberty in industrialized societies.
It can, however, occur at all ages. Typical acne affects the skin of the face, chest, and back and rarely the neck and upper arms of teenagers and young adults. Because acne typically occurs during a time of dramatic physical and psychological changes associated with the development of one’s body image, it can exacerbate social withdrawal and even depression. Left untreated, severe acne can lead to disfiguring scarring which can be difficult to treat. Several myths exist about acne.
