I hear you, my derm said the same thing, that it should heal in time, but that may be 10 or 20 years from now. He also said it was an allergy. If I apply lip balm several times a day my problem goes away too, but if I stop it comes back, so be wary if you stop, your hopes may be shot down, as I was in Europe for the summer and applied every day several times a day lip balm and they were like I never had the problem, but I stopped when I got home cause I didnt want to become addictive and for it to get worse.
I'd rather apply it when there was something important like a trip, family outing etc... I have pure glycerin because I make my own creams but I thought I shouldnt apply it because it is not 100% natural, what does it do for you?
