Lip allergy or...: Persistent chapped lips may 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 lip-licker (it's her habit). Once cracked, lips get irritated by foods and juices. Vaseline itself is just oil and thus shouldn't cause allergies.
