What should I do if my child's lips are constantly dry, cracked, and peeling?

1. Ensure your child drinks enough water and maintain appropriate indoor humidity. Apply lip balm specifically designed for children, avoiding adult products. 2. Increase intake of fruits and vegetables in the diet to supplement vitamins B2 and A. 3. Advise your child not to lick their lips frequently, as saliva evaporation removes moisture from the lip surface and worsens dryness and peeling. 4. If the indoor environment is dry, use a humidifier to increase air humidity and reduce moisture loss from the lips.
