I'd vote against steroid cream too - for that thinning reason. I'd probably go for something quite thick and gunky and oily (to really get into that dry flaky stuff), but if there are raw patches you might need to watch what you put on.
not sure what sudacreme is, but it might be largely cetamacrogol - thats a really basic cream that my GP recommended years ago - its what they use a a "base" for other things, but its actually quite simple and good on its own. You might need to ask at a compounding pharmacy, because it isn't high tech enough to be a branded item.
Here, I'd go and talk to a pharmacist about that kind of thing and see what they recommended. Is that something you could do in the US?
