Little know but incredibly helpful is a product called bag balm. It is very soothing and really works well. It has a very greaselike texture and can be really worked into the cracks.

You can also slip on some thin latex gloves over the hands after applying the balm. This will keep the balm very moist and work longer into the skin. I would not leave gloves on all the time, just for a bit to let it work in. The balm will dry up some but still leaves the hands pretty supple.

The main use is to keep cow utters from cracking and stay moist. It is worth a try and very inexpensive; can't hurt.
