If you think dry skin is nothing to worry about, consider instead worrying about patches of red, inflamed skin on your hands called eczema. Eczema can be a chronic or allergic condition, but it can also appear on skin that's irritated, dehydrated or sensitive. What's worse is that treating it can be difficult.
Moisturizers can play an important role in preventing hand eczema as well as treating the condition before it progresses to the point that you'll need prescription medications. Look for moisturizers with ingredients that provide a barrier between your skin and the environment, such as jojoba or other oils, lanolin and petrolatum (petroleum jelly).
