There's no doubt about it, dry skin is as uncomfortable as it can be unattractive. But instead of dealing with ashy, itchy skin that's thirsting to be quenched, give it what it wants and relieve your discomfort. The path to soothing your dryness might not be as complicated as you think. If you feel as if you've done everything possible to soothe your dryness, then it's time to rethink what you're doing and try something new.
Jump in a warm shower or, if you prefer, a warm bath. Hot water is seriously an enemy of your skin and taking super-hot showers or baths is just treating your skin wrong. Cut back on the time you spend getting clean as well. Limit baths and showers to 15 minutes or less.
Wash with gentle soap-free cleansers when taking your shower and forget about using regular soaps on your skin. It's already dry and irritated and those will only make matters worse.
Blot your skin dry with a soft, fluffy towel. Rubbing will steal the oils from your skin that help keep you moisturized, and that will only make matters worse. A gentle patting action does the trick---but not too much. Pat the excess water for 20 seconds or less. If your skin isn't damp, you've over-dried.
