ehh im 18 and i have been dealing with this problem for about five years now and ive had a biopsy and it showed that there was nothing rong with my lips except for yeast shit. My derm gave me cream and that got rid of the yeast but not the peeling. Last summer i decided to go swimming with my friends (something i would usually never do) and the outside of my bottom lip didnt turn white and soggy like it usually would. I was extremly happy. The inner part of my bottom lip where it meets with my top lip still peeled and turned white and soggy but it was tolerable considering the improvement of the side of my lip being healed. I dont know how it healed but it just did. Then a few months later during the fall i decided to drink alcohol and i ended up throwing up and then when i looked in the mirror i noticed that the outside of my bottom started turning white and soggy again. I havnt been able to get it to heal again and its really bothering me cause i dont know how i was able to heal it before. plus this cold weather isn't helping either. just something i thought i would share with you guys.
