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.
Acne myths
12. • Cosmetics
Cosmetics don't necessarily
worsen acne, especially if you
use oil-free makeup that doesn't
clog pores (noncomedogenics)
and remove makeup regularly.
Nonoily cosmetics don't
interfere with the effectiveness
of acne drugs.
