Traditionally many of us have combatted extremely dry skin by rubbing a commercial skin-care product on it. But it may be time to moisturize your skin from the inside out.

"Even though they're not diseases, extremely dry or excessively oily skin can pose problems. Diet, environment, and soaps can all add to your skin problems. With so many skin-care products available, it's easy to choose the wrong kind for your particular type of skin."

Drinking plenty of water and taking in the right kinds of oils helps to moisturize your skin. Vitamin A repairs skin, so eat vegetables rich in Vitamin A.

Stay away from drying agents like acetone, benzoyl peroxide, camphor and citrus. Forego long hot showers or baths as they will only make extremely dry skin worse. Brush your skin with a dry loofah daily, to remove dead skin.

Unlike your average commercial skin-care product, the best moisturizers are good enough to eat. If it's not safe to eat, don't use it to moisturize your skin. Avocado, olive oil, aloe vera, are a few examples of edible moisturizers.
