Here are some common myths — and some real facts:

MYTH: People get acne from poor hygiene.

FACT: Acne begins below the surface of the skin when the hair follicle becomes plugged. Bacteria that cause inflammation in the hair follicles of your skin may contribute to the formation of acne pimples and blackheads. However, the blackheads aren't plugged with dirt, and the pimples simply won't get better with repeated washing. In fact, over-washing may actually irritate your skin.

MYTH: Eating greasy, fried foods or chocolate causes acne.

FACT: No one has been able to prove that chocolate causes acne. The only way fried foods may promote blemishes is if the oil in which they are cooked gets onto your skin and isn't completely washed off. Sometimes a poor diet reflects a stressful lifestyle. In some people, stress itself can trigger an outbreak of acne by increasing production of hormones.

MYTH: Using makeup causes acne.

FACT: Some makeup can promote the clogging of pores. Look for makeup labeled "non-comedogenic," which is specially formulated not to clog your pores or aggravate skin.

MYTH: Washing your face frequently will prevent acne.

FACT: No matter how much you scrub, you can't prevent clogged pores. In reality, washing too frequently, or with harsh cleansers, can actually make it worse. Your body may produce more oil to combat the dryness. Try a mild cleanser such as Cetaphil® cleansers, formulated for all skin types. If you have already have acne, talk to your dermatologist about medicated cleansers and gels. Learn more about skin care.
