The word acne is a derivative of the Greek word acme, referring to the prime of life. This corresponds with the usual age of onset of acne, which tends to be in early puberty. More than 80% of adults have had some experience with acne. [40] Clinically significant lesions consist of an open comedone, which corresponds to the term blackhead. [40] Closed comedones correspond to whiteheads. Additional inflammatory lesions include pustules, papules, and cysts . [40] The most aggressive forms of acne have chronic scarring coexisting with active inflammatory foci.
