For an unfortunate minority, however, acne can cause extremely painful, cyst-like lesions that leave deep scars. Such severe cases usually require the attention of a dermatologist. Contrary to popular belief, diet plays a relatively minor role in acne frequency or severity. But certain drugs, stress, industrial chemicals, and some bacteria can trigger acne episodes. Avoiding such triggers can be a first step toward minimizing or eliminating skin eruptions altogether.
Persistent acne is severe and leaves scars.
Keep all acne-prone areas very clean, using soap and lots of water to rinse. Pat areas dry, don't rub or scrub skin. Wash acne-prone areas with lukewarm or tepid water, not very hot or very cold water. If your doctor prescribes Retin-A for your acne, stay out of the sun as much as possible. Don't cover acne outbreaks with bandages or tight-fitting clothing.
