Just because the corners of your lips no longer peel as much, and you think its because theres no inflammation doesnt prove anything. And Inflammation isnt always as noticeable as having swollen red skin.
And you say that when they peel once in awhile the skin underneath is "healthy". If it was healthy then it wouldnt be peeling.
And if your so positive then why dont you try an aggressive anti-inflammatory treatment like I did with the Cyclosporine.
