What causes acne

[Ann]

Acne is a common skin disorder resulting from the action of hormones
on the skin's sebaceous glands. This leads to plugged pores and
outbreaks of lesions commonly zits or pimples. Acne is common in
adolescents and young adults. Almost 85 percent of people between the
ages of 12 & 24 are affected by acne. For most, acne generally tends to
go away by the time they reach the age of thirty.

Doctors believe acne can result from several related factors including
heredity, increase in hormones (androgens), hormonal changes related to
pregnancy or birth control pills can sometimes cause acne.

Acne usually occurs on the face, neck, shoulders, back, and chest. Acne
can be a heredity factor.
