Get Out of the Bath!
If you suffer from habitually dry skin, one of the best skin moisturizing tips we can give you is to stop bathing. Not entirely, of course, but enough to let your sebaceous glands replenish your skin's natural layer of oil that's stripped away during washing. Both hot water and regular soap rob your body of its moisturizing oil, so basically, the more you bathe, the harder it is for your skin to keep itself moisturized. Cutting back a daily bathing regimen to three or four times a week should do the trick for most people, though those with severe xerosis might want to consider visiting the tub only once every seven days [source: Dermasil Labs].
If this sounds too extreme, try using warm water instead of hot when washing, and limit your bathing time to 15 minutes or less. Also, use soap only on the critical areas -- namely the armpits and genitals -- and use cleansers like Cetaphil or Aveeno on the rest of your body. Following these steps will help you retain some of your skin's oils, though it won't be as effective as forgoing the bath altogether.
