My partner has problems where his feet do the same thing that your fingers are doing because they get so dry.
Here is what he does for his feet, so it stands to reason that this would work on your hands too. He has some avon products for his feet so why not just use foot lotion on your hands.
First he soaks them in as hot a water as he can stand with a little epsom salt. Then right after he applies the Avon Foot Cream, puts on his socks, and sleeps with them on. He's been doing this for about 2 weeks and his feet don't crack anymore. And they are wickedly softer than they were before as well.
