Acne is caused by plugged hair follicles and bacteria, resulting in pimples on the face and body. It is worsened by hormones during puberty and certain medications. Diet and stress can also exacerbate acne. The signs include blackheads, whiteheads, papules, pustules, cysts and nodules. Treatment involves gently cleansing the skin while avoiding excessive touching, scrubbing or sun exposure. Myths such as greasy foods and dirty skin directly causing acne are untrue.

10. Acne myths
• Greasy foods
Eating greasy food has little to no
effect on acne. Though working
in a greasy area, such as a
kitchen with fry vats, does
because the oil can stick to the
skin and block the hair follicles.
This further irritates the skin or
promotes acne.

11. • Dirty skin
Acne isn't caused by dirt. In fact,
scrubbing the skin too hard or
cleansing with harsh soaps or
chemicals irritates the skin and
can make acne worse. Though
it does help to gently remove
oil, dead skin and other
substances.

Cosmetics don't necessarily
worsen acne, especially if you
