so you found the cause but now you have to "manage" it with zinc and vitamin a supplements everyday. I thought you didn't want to manage it. there is another forum where a theory is vitamin A overdose is the cause of peeling lips from taking vitamin A supplements. also, how come all these people have been to doctors and specialists but none of them have said anything about zinc being the cause. I think you are doing a little too much research on web, give it up and just look for the natural cure which is water. but if you want to go 10 years without getting your lips wet that is up to you.
