Perhaps if the lips still peel without the use of coconut oil this is not the problem.
The only thing that would tie in with my strange bouts of redness/inflammation and peeling would be what I am eating. It could be that although toothpaste exacerbates the underlying issue to a lesser or greater degree this is not actually causing the problem.
Perhaps this is why my lips sometimes peel even when I eat clean. It's incredibly depressing not to know what dietary changes to make. For the first time in my life perhaps I should consider an elimination diet. http://salicylatesensitivity.com/forum/comments.php?DiscussionID=920
Maybe someone else here could join me in this to see if it makes a difference?
