Acne

Acne is an infection of the skin, caused by changes in the sebaceous glands which usually happen during puberty. Acne can be treated with a solution of Bubotuber pus. Eloise Midgen was known to have a bad case of acne and many of her colleagues at Hogwarts School used her as the standard against which really bad acne was to be measured.
