What causes chapped and peeling lips?
Under normal circumstances, persistently dry and peeling lips may be caused by environmental factors, lifestyle habits, cheilitis, vitamin deficiencies, Sjögren's syndrome, or other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. A detailed analysis is as follows:
1. Environment
Dry and windy climates can accelerate the evaporation of moisture from the skin surface, potentially impairing the lips' stratum corneum's ability to retain moisture, leading to chapping and peeling. It is recommended to use a humidifier to maintain appropriate indoor humidity and apply lip balm to relieve dryness.
2. Lifestyle Habits
Frequently licking or biting the lips can accelerate moisture loss from the lip surface and damage the natural protective barrier. The use of irritating cosmetics may also directly harm the delicate skin of the lips, causing dryness and peeling. It is advised to correct these unhealthy habits, choose mild and non-irritating lip care products, and maintain adequate hydration by drinking sufficient water.
3. Cheilitis
Cheilitis is a lip condition caused by various factors such as allergies, infections, or environmental irritation. It can damage the skin barrier of the lips, increase moisture loss, and lead to dryness and peeling. Symptoms may also include redness, swelling, itching, and pain in the lips. It is recommended to apply moisturizing lip balm and follow medical advice to use medications such as cetirizine hydrochloride tablets, loratadine tablets, or fusidic acid cream for treatment.
4. Vitamin Deficiency
Vitamins from the B group and vitamin A play important roles in maintaining healthy skin. Deficiencies in these vitamins may impair skin repair and regeneration, resulting in dry, dehydrated lips and peeling. Other symptoms may include rough skin and brittle hair. It is recommended to increase intake of vitamin-rich foods such as whole grains, nuts, leafy vegetables, and fruits, and to take supplements like multivitamin B tablets, vitamin B2 tablets, or vitamin A softgels under a doctor’s guidance.
5. Sjögren's Syndrome
Sjögren's syndrome is an autoimmune disorder in which exocrine glands are attacked by the immune system, reducing secretion from glands such as salivary and sebaceous glands. This leads to dryness of the lips and other skin areas. Additional symptoms may include dry eyes and joint pain. It is recommended to drink plenty of water and, under medical supervision, use medications such as hydroxychloroquine sulfate tablets, methotrexate tablets, or levamisole hydrochloride tablets to alleviate symptoms.
To relieve dry and peeling lips, it is advisable to correct unhealthy habits in daily life, drink sufficient water, use non-irritating moisturizing lip balms, maintain a balanced diet, and avoid licking or biting the lips.
