Congrats on your progress and thank you for sharing and supporting others in the community, jsl123! Very interesting to see one lip heal so much more quickly than the other, without a notable difference in how you treat them.
My condition spread from bottom + upper middle triangle to covering both, and then at some point I think the top lip was nearly healed, and then I did something or a series of things (likely drinking, smoking and other types of ill shit) that brought it back to both lips. Now strangely they seem to be ready to peel at different times, even after I peel them both at once. Chinese medicine says that each lip is connected to different internal organs, I think upper lip disorders exhibit symptoms of stomach disorders.
Anyway, just some thoughts from a toxic Westerner -- I'm sure all my internal organs have a disorder, which I will remedy with time. Keep up the fight!
