Dry skin is an uncomfortable condition marked by scaling, itching, and cracking. It can occur for a variety of reasons. You might have naturally dry skin. But even if your skin tends to be oily, you can develop dry skin from time to time. Dry skin can develop on any part of your body. It’s most likely to affect your hands, arms, and legs. In many cases, lifestyle changes and over-the-counter moisturizers may be all you need to treat it. Exposure to dry weather conditions, hot water, and certain chemicals can cause your skin to dry out. Dry skin can also result from underlying medical conditions.
