its funny that you say this. becasue my whole lip problem began when i was in a climate were chapped lips is very common and i only bite the top bit in the middle of my upper lip. was it because it was just a bit dry? who knows but i find it very interesting. also as soon as i left that climate my lips went back to normal(not chapped) and then i went on holidays to a very cold climate also were chapped lips is very common. and bang ec over both my lips. It wasnt gradual or anything like that it was not the and then it was there in 1 day turn around bizzare. although while on holidays i now believe my lips would of been chapped due to the freezing cold and windy temperatures.
anyways sirpies in regards to pro topic. does pro topic cure people from exzma? or is it just to help treat the condition. like i say i have only briefly looked into exzma. most of my derms i saw told me exzma and psorosis on the lips is very unlikely.
