My Dad and I get this every winter - the finger tips crack and bleed (I hates, I do).

O'Keefe's Working Hands, in the green salve jar, is a gift from the goddess, let me tell you.

When it is very bad, I load up a bandaid with the salve and strap it over the crack and sleep with it at night. May take two or three nights to heal enough to leave the bandaids off. Really good stuff, though.
