Won't hurt: The site offers useful info for skin care. Other things you can do: eat healthful meals, use lip balm with spf, avoid very hot showers or long baths (they strip body's natural oils), check skin for signs of sun damage (especially if you're in the sun or harsh weather a lot), bring new/changing skin lesions to fp's or dermatologist's attention.

Protect: Avoid things that make you break out, soaps ; wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot. Use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.
