Hi, Marci!

Welcome to NeuroTalk!
Your struggle sounds like a nightmare, I'm so sorry you have to deal with this. I'm fortunate to have escaped most allergies but do have patchy sensitive skin. My saviors have been Cetaphil cleanser & lotion, and Phisoderm. I'm not sure if you've tried either, but it sounds like you might be better off testing a small area before committing to a full use of anything.
We have a forum dedicated to allergies and you may find more knowledgeable folks to help you there.
