How to properly treat dry and cracked lips in children?

Patient's question:

My child is 8 and a half years old. Every winter, especially this winter, he has never had this problem before. His lower lip is always cracked. He has tried many methods, but none have completely cured it. I wonder if you can provide a good treatment method.

Doctor's answer:

Hello, treatment for dry and chapped lips
1. Use lip balm
2. Apply lipstick
3. Take vitamin B complex
4. Hydrate
5. Do not lick your lips
6. Avoid allergies to toothpaste, flavorings, candies, gum, mouthwash, etc. Baking soda is a better choice for brushing teeth
7. If you don’t have lip balm on hand, you can rub some oil from the sides of your nose on your lips, which is considered the best natural remedy
