However, I have a little hesitation about your conception of peeling/crusting. Personally I make a distinction between these two terms I believe evident that while using any cream, no crust can be formed. In the meantime, the peeling can keep going.
So actually you still don't know if your lips would be 'normal' if you stopped the use of lip balm. Why don't give it a try?
I see that you can take high resolution pics. Can you share one of your lips right now, as they are, at least the middle of your top lip, which is, if I've clearly understood, the only affected area? Thanks!
