Jojoba oil is supposed to be very good; I've never tried it. I have very dry skin too, I use Johnson's 24 Hour Moisture on my arms and legs, Aveeno for sensitive skin on my face. The Badger Balm people make some body butters that work well, although they can feel a bit greasy. I use Badger's Cuticle Balm on my nails and cuticles.

For hands I have a couple of different ones -- Philosophy Handmade ($$$ and it no longer comes in the big jar ) and Neutrogena's Norwegian Formula.

I have mild psoriasis on my elbows, when it acts up I slather on Gold Bond Ultimate Healing.
