Dry, cracked, and peeling lips can be caused by a variety of reasons, one of which is cheilitis. Cheilitis is an inflammation of the lips, usually caused by allergies, infections, or environmental factors. However, dry, cracked, and peeling lips don't necessarily mean cheilitis; it could also be due to dehydration, dry weather, malnutrition, or certain lifestyle habits.

If chapped lips are accompanied by pain, swelling, or small blisters, it could be a sign of contact cheilitis or infectious cheilitis. Contact cheilitis is usually caused by contact with certain allergens or irritants, such as ingredients in lipstick, toothpaste, or other cosmetics. Infectious cheilitis may be caused by viral, bacterial, or fungal infections. If chapped lips are accompanied by fever, increased pain, or significant swelling, this could be a sign of a more serious infection and requires immediate medical attention.

Another cause is environmental factors, such as cold, dry climates, or prolonged exposure to air conditioning, all of which can lead to chapped and peeling lips. Poor lifestyle habits, such as smoking, drinking alcohol, or insufficient water intake, can also cause this symptom. Malnutrition, especially a deficiency in B vitamins and iron, can also cause chapped lips.
Key points to note: If chapped lips are accompanied by severe pain, swelling, bleeding, or fever, this could be a sign of infection or other serious illness, and you should seek medical attention immediately. Avoid self-diagnosis, as there are many causes of chapped lips, and a professional medical examination is necessary to determine the specific cause. At the same time, avoiding the use of cosmetics or skincare products that may cause allergic reactions and maintaining good lifestyle and dietary habits can help prevent chapped lips.
