Acne vulgaris and its resultant scars are associated with significant social and academic difficulties that can last into adulthood. During the Great Depression, dermatologists discovered that young men with acne had difficulty obtaining jobs. Until the 1930s, many people viewed acne as a trivial problem among middle-class girls because, unlike smallpox and tuberculosis, no one died from it, and a feminine problem, because boys were much less likely to seek medical assistance for it. During World War II, some soldiers in tropical climates developed such severe and widespread tropical acne on their bodies that they were declared medically unfit for duty.
