My lower lip is always chapped & peeling for 3yrs now.lip balm doesn't help either.help?

See dermatology: There are many causes of chapped/peeling lips. Long-standing dry skin can be due to dehydration or a reaction to an allergen (whether it's a chemical in lip balm or in food). But it's important to make sure with a dermatologist that there isn't an underlying inflammatory disorder or, less likely, a premalignant/malignant condition. In the mean time, use a thicker ointment like vaseline or Aquaphor
