Rachylou, I've got the horribulous dry skin that I further aggravate by being a gym rat (frequent showers, swimming pool.). Most winters I have band aids on half of the fingers of my hands due to cracked exema fingers. I've used everything, and still do. Currently I've got Johnson's baby lotion and baby oil, Aveno Baby FF daily lotion, Bio Oil, Cereva, and Eucerin on the go. (And that is just for my body!)
Honestly, though, the very best thing when I am at my most miserably dry is Criso shortening. Been using it since I was 14 and read about in some make-up myth buster book. Doesn't sting or hurt in any way. No scent or other things to be off putting. Slather tip to toe before bed. Near instant relief and supple soft skin the next day. Unfortunately no glamourous pots or presentation.
