Is there a cure for chronic dry skin, particularly for the hands and feet?

I already use lotion. I've tried all different types and I've used the lotion specifically for feet on my feet. I also use the pumice stuff for my feet, too. It all helps, but only when I put lotion on/use the pumice stuff. Will the dryness ever go away where I won't have to use lotion so often? What causes such dryness?Is there a cure for chronic dry skin, particularly for the hands and feet?
Hi there, I have tried so many different things over the years and been prescibedcreams from the doc but only last month my sister who is a pharmacist told me about a cream called Zerobase, Liquid Paraffin Cream, works wonders for me, just a sugesstion, good luck.
