Hydrate your body by drinking lots of water and apply aloe vera oil more remedies at http://www.wellnesstalk.org/dryskin.html

For dry skin, mix sugar and olive oil together to make a thick paste. Stand in the tub and use this mixture as a scrub over your skin before showering. DO NOT USE this on your face. To help with oily skin on your face: first of all do not wash your face too often! This only tricks your skin into thinking it is too dry and it will produce more oil. Only wash your face in the morning and before you go to bed. Use a gentle cleanser or mild soap. I like a pure goats milk soap for my face. After washing and rinsing, wet a cotton puff with witch hazel and wipe it over your face. Do not rinse, just let it dry and follow with an oil free lotion. Once a week use a facial scrub, either one you buy or you can simply add something abrasive to your daily face wash or soap, Such as sugar, sea salt, crushed almonds, or even oatmeal. Scrub GENTLY. The trick is to not strip the skin of too much of the natural oil it produces.
