I do have a bunch of experience with this. I work outside in the winter, (29yrs.) which usually lasts in upstate NY from Nov. to late April. To compound that, I handle tons of paper which also robs the skin of it's natural moisture and elasticity. I have tried just about everything, and have settled into a routine that while far from a cure, seems to help a great deal. To start with I use only high quality skin cream lotion. There are several good brands out there and they all seem to do a pretty decent job. I also use a paraffin bath, like those used in a nail salon.
eg.

I first coat my hands with lotion, and then dip them 4 or 5 times into the hot wax allowing it to slightly harden between coats. Put on a pair of very loose plastic gloves or better yet, some plastic bags and let it sit on the skin for 20 min. Remove the bags, peel off the wax, and put it back in the bath for reuse.
You will be amazed at how much moisture this puts back into the skin.
Another great tip is get into the habit of wearing disposable plastic gloves around the hose when doing everyday chores. Dish washing is extremely tough on the hands. And again, put on lotion before putting on the gloves.
With all the flu and such going around, people often get in the habit of using hand sanitizers like Purell. While sometimes necessary in a pinch, the alcohol in that stuff helps them to crack by taking moisture out of the skin. Instead I found using a soap designed for dentists works best. We all know how many times a day they wash their hands, but next time take a look, they are always soft. You can find them online. Septoderm, Lysol IC, and DermaRite/DermaRich are a few of the choices.
Lastly, when all else fails and a crack does occur, I use a product called Robby's skin protector.
http://www.robbys.com/skin_protector.php It a basically a glue, that unlike NuSkin, dries quickly, and unlike superglue comes with a brush applicator. I've used this stuff between songs and it's dry and ready to go within a very shot time. two coats work great. You can find it at practically any bowling center in the bowlers aids vending machines. Hope this helps....
