Jan. 22, 2010 -- (HealthDay News) -- The exact cause of acne isn't understood, but the American Academy of Dermatology says four factors are involved: too much oil, clogged pores, bacteria, and inflammation.
The academy offers these skin-care suggestions designed to help manage acne:
Gently clean your face one or two times per day with a gentle skin cleanser and lukewarm water. Excessive washing, on the other hand, can irritate the skin and make acne worse.
If your hair is oily, shampoo daily to help prevent oil from getting to the skin.
While foods aren't believed to cause acne, in some people, certain foods can make acne worse. If you know which foods seem to aggravate your acne, avoid them.
Use oil-free makeup and skin products.
Avoid getting hair products, such as sprays or gel, on your face.
If you have acne, your dermatologist may recommend a prescription or over-the-counter treatment.
