Acne

Acne - or Acne Vulgaris - is a common skin condition, identifiable by areas of scaly red skin (seborrhea), blackheads and whiteheads (comedones), pinheads (papules), pimples and nodules (pustules), and possible scarring caused by one or all of the previously mentioned characteristics.

Acne occurs more often during adolescence, and can often continue into adulthood. Acne in adolescence is commonly caused by an increase in testosterone, something that happens in both genders.
