Acne is a problem for many teens - and for some adults, as well. These clusters of pimples and blemishes usually occur on the face but also on areas such as the back and shoulders.
While the causes of acne aren't fully understood, heredity and hormonal changes are thought to be prime culprits. Many people believe that greasy foods or fatty sweets such as chocolate may cause an outbreak, but the National Institute of Arthritis and Musculoskeletal and Skin Diseases says that's a myth. Another common myth is that dirty skin causes acne, the institute says.
Other factors, while they don't cause acne, can make it worse. These includeuse of oil-based cosmetics, stress, tight clothing or hats, and abrasive facial cleansers. The institute warns against popping, squeezing or picking at acne, which are likely to worsen the skin's appearance.
However, many doctors tend to blame poor nutrition and lack of exercise for acne. Dr. Nicholas Perricone in his "The Acne Prescription" suggests an easy-to-use acne-clearing diet that is designed to diminish inflammation and pore clogging associated with acne.
