Through lots and lots of experimentation, I found out I am allergic to almost every brand of lip
balm including Burt's Bees, Carmex, Blistex, etc.
After that happened all hell just broke loose, my lips began getting tiny tiny red bumps which also had this yellow liquid seeping out. I would put Aquaphor (one thing I was not allergic to at the time) on it but it looked like it'd only get worse. so I just let it dry out and that seemed to help.
