I have the same problem too.. It would crack and my friends would be looking at me with this very concerned look hahaha. It would hurt real bad and I would do all sorts of things to peel it off (it hurts like mad )

Anyways, lip balm and lots of water should do the trick. My favourite lip balms are: Crazy Rumors and Avene Cold Water. Both do not have SPF protection btw. Crazy Rumors are the best everrrr
