Hi,
1. NEVER
2. NEVER also
3. I don’t understand the question.
4. No I rarely use chapstick before the exfoliative cheilitis.
5. No
To conclude, I would say that, in my case, the exfoliative cheilitis comes from a bite to the upper lip. First, it just affects the central area but after few weeks, it extends to the whole upper lip. Then (after 3 or 4 years), because of using creme, the probleme goes also to the bottom lip.
Good luck, [End]
