Frequent chapped lips can be caused by a variety of reasons, including environmental factors, dietary habits, and health conditions. This symptom may be due to dry skin, vitamin deficiencies, or certain health problems.

Environmental factors are a common cause of chapped lips. In dry, cold, or windy environments, lips easily lose moisture, leading to dryness and peeling. Frequent licking of the lips can also cause dryness, as saliva evaporation draws away more moisture. Dietary habits also affect lip condition; deficiencies in vitamins A, B complex, C, or E can lead to dry and peeling lips. Certain food allergies or irritating foods can also cause chapped lips. Some health problems, such as oral candidiasis and chronic cheilitis, can also cause chapped lips.

If chapped lips are accompanied by pain, redness, swelling, heat, or other unusual symptoms, this could be a sign of a health problem and requires prompt medical attention. Chapped lips may be related to vitamin deficiencies, but it's best to consult a doctor before self-supplementing with vitamins to avoid excessive intake that could lead to other health issues. Individual differences are significant, so seeking professional medical diagnosis and advice is crucial for persistent or severe symptoms.
