It's probably Dyshidrotic Eczema. It starts in the sweat glands of the hands or feet. Applying lotion and such will not help. You need to see a Dermatologist for Rx creams that will heal it. They aren't sure what causes this, but some speculate it has to do with high stress.
BTW, it's not contagious and you really can't prevent it. If you can't see a doctor, cortisone creams will help.
