I use pure lanolin. You can find it in the Baby aisle. Nursing mothers use it to sooth cracked nipples.
I also use Beeswax Salve i order from a lady in Wisconsin, Julie. I buy 4 at a time in 1lb jars. Google: Stassel's Beeswax Salve. My daughter with eczema swears by it claiming is the only thing that keeps moisture in her body.
