Out of the blue, my lips are so dry that they are swollen, peeling and red beyond the margins of my lips. I have tried every lip treatment.

Lip dryness & ec. Persistent dry lip may be lip eczema, which can be treated like skin eczema, using hydrocortisone cream plus Vaseline or Aquaphor to retain moisture. Sometimes, lipsticks or lip sunscreen chemicals are causing an allergic reaction on the lips. Other times, a person is a primary lip-licker (it's her habit). Once cracked, lips get irritated by routine foods and juices. A doctor can sort things out.
