The term acne is derived from the Greek word acmé or acné, meaning foam or summit, and denotes a skin disease that is widespread in the young population, characterized by the appearance of characteristic lesions on the skin.
About 95 percent of adolescents and young adults (13-25 years old) are interested in it (source: Do you speak science?).
In a minority of cases, acne may persist in an attenuated form into adulthood or appear after the age of 30 in people who had suffered little or no acne in adolescence. This second eventuality mainly affects women, for hormonal reasons.
