Firstly, I read a post you made about 18months ago which was useful because you clearly have lifelong peeling (much like I do).. actually I found it a very sad read because the way you wrote that post illustrated just how restrictive a mentality you develop with this problem... all social situations are effected, and also anticipating social situations. It read how it feels (very stifling). I can relate to how you feel in every minute detail.
So, you mentioned previously you have a health condition, is it diagnosed? if so what is it?
Secondly, it appears you've tried the leave alone/moisture and various different presription anti-fungal/corticosteroid ointments which didn't help long term. I'm the same and I think some people have a more systemic problem.
Perhaps if you haven't already is it worth getting your thyroid checked out? I know I keep mentioning it on the board at the moment but I'm excited about what might turn up. Thyroid and peeling lips has been mentioned numerous times over the years on this forum, there's about 10 hours worth of reading to be had. It's definately worth a check if you haven't already??
