I stopped using the calendula after two weeks. It did stop my peeling as well but didn't heal me. So on a whim I decided to start using my doctor prescribed desonide again after not using it since initially getting ec. So far the desonide is the most promising thing I've used. My lips are actually returning to normal. I can only tell from other peoples reactions because I don't get the disgusted look anymore lol. But I've only been on it for a week. And I switched my toothpaste and started using biotene toothpaste,mouth wash, and oral gel as well. I would find it funny if my ec was caused by xerostomia cause if that's the case I wish i could have had these 8 months of life back.
