Okay so I'm my opinion to cure self induced ex, which I have from years of mouth breathing when I slept and constant Chapstick and biting my lips, is obviously letting it heal itself. You've cause a lot of trauma to your lips and in no way will peeling it off and using a cream heal it. That just wouldn't make sense. The only way is to let it protect itself and apply some moisture throughout the day because things do heal a lot faster in a moist environment.
