i am a heart patient and get dyhydrated a lot. my lips peel all the time and so sore and dry till they crack and bleed. Anyway. i was told that drinking a lot of water a day and a good lip moisturizure works and helps them from being so dry and peeling. also A and D ointment before bed everynight helps as well. let me know if this helps anyone. it helped me a lot. but the trick is hydration and lip moisturizure.
