Peeling skin in the middle of the upper lip can be a sign of cheilitis, but it can also be caused by other factors. Cheilitis is an inflammation of the lips, usually caused by allergies, environmental factors, or certain lifestyle habits. If accompanied by redness, swelling, pain, or a burning sensation, this could be a sign of allergic cheilitis or contact cheilitis. If peeling occurs after meals or contact with certain foods, it may be cheilitis caused by food allergies. Another possibility is related to weather changes, such as dry winters, which can cause peeling lips; this usually does not involve obvious inflammation.

Key points to note: If peeling is accompanied by severe pain, swelling, or purulent discharge, it may be a sign of infection and requires immediate medical attention. A common misconception is that all lip peeling is due to cheilitis; in fact, peeling may be caused by dehydration, vitamin deficiency, or environmental factors. It is important to emphasize that for persistent or severe symptoms, a professional medical diagnosis and advice should be sought.
