i used to have really bad chapped lips which sometimes r too dry that they bleed when i smile. the reason is the toothpaste i used which were too harsh for me. the doctor said i should top using Darlie toothpaste and try something milder like fresh n white. u should stop using Darlie toothpaste is u r using it. try body shop's vitamin E lip moisturizer. it has healed my chapped lips.
