I was viewing your cheilitis pictures and my problem is exactly the same as yours.
I have been exploring the Amalgam filling theory; however, I am certain that this problem was caused by taking the powerful Acne drug, Accutane. My thinking is that my fillings might be a roadblock to curing this problem.
Did you by any chance take Accutane???? Or does anybody else have Accutane-induced cheilitis????
