Exfoliative cheilitis is a type of skin lesion on the lip mucosa of unknown cause. Generally, the skin on the lips is delicate, and exposure to certain external stimuli can cause dryness, cracking, bleeding, and peeling. This condition is often associated with certain bad habits of the patient. For instance, due to dry weather, a patient might frequently lick their lips, leading to long-term irritation and consequently causing cracking and bleeding. It could also be possible that the patient has come into contact with some allergenic substances. This is commonly seen in females; for instance, an allergic reaction triggered by applying lipstick or lip balm can lead to peeling of the lips. In such cases, it is generally advised that the patient identifies and avoids the cause. When the patient's skin shows signs of crusting and peeling, it might generally indicate an improvement.
