what cause chapped lips
Chapped lips (also cheilitis simplex or common cheilitis) are characterized by cracking, fissuring, and peeling of the skin of the lips, and are one of the most common types of cheilitis. While both lips may be affected, the lower lip is the most common site. There may also be burning or the formation of large, painful cracks when the lips are stretched. If chronic, cheilitis simplex can progress to crusting and bleeding.
