You don't have to post picture. If its same as mine was I understand how it looks. I dont know what to say about your triangle, because my triangle appeared periodicaly and most of time it wasnt there. But my bottom lip was always affected and now its healing. Every day it looks slightly better than day before. Try my method, maybe it'll work. Just don't ever force peeling. Put lip balm now if your triangle is raw, wait one or two days than start soaking with water and rubbing it off. But dont force it off even then. Just take it easy. Point is, dont expose raw skin. It will just harm it and restart cycle again.
