I also have some eczema/dry skin problems and one thing that I've found helps is not showering every single day. I used to shower once (or sometimes twice) a day, and it made the skin on my elbows and knees extremely tight, dry, and itchy. I now shower every other day (I still use deodorant and change my clothes) and haven't had nearly as many issues. That being said, I am fortunate because I don't have a lot of body odor and I don't sweat very much, so I can reasonably get away with not having a daily shower.
