I'll third the rec for the Neutrogena Norwegian formula stuff, although I don't know how it works on areas larger than hands. I like it because I can wash my hands pretty frequently during the day without losing the benefits of it. (Upon further reflection, I realize this makes me sound like a germaphobe. Note: I have not gone Monk-like. I just touch fairly icky stuff fairly often. I've had two labs on parasites in poop in the last week, for instance.)

One of the simplest tricks that I didn't know for the longest time (which likely means everyone else in the world does know it) for keeping skin from drying out is to moisturize like crazy right after a shower, when the room is still steamy and your skin is still receptive. It's kind of awesome how much of a difference it makes.
