This is a recurring problem that I have tried to hide/cure with many ointments. Including various vasaline types, lip
chap (with sunscreen protection), lip
conditioner/balm (blistex sunscreen protection), also have tried Cortate Hydrocortisone ointment. Which only seems to glosson my lips and make them seem to be more red.
I have also tried "Ihle's paste" for rashes, mostly used for relief of dermatitis and diaper rash, which seems to help momentarily, but only for 10 or so minutes.
