What causes dry lips in children?

The weather is getting colder and colder, and autumn and winter are coming soon. We all know that the skin is particularly dry in this season, whether it is adults or children. Many children have dry and cracked lips in autumn and winter. And because children don't know how to take care of themselves and like to lick their lips, it is very painful, and in severe cases, it may bleed. So what is the reason for children's dry lips?

The red area around the human lips is called the "vermilion border". Its moisture is maintained by the local abundant capillaries and a small number of underdeveloped sebaceous glands. Due to the low humidity and strong winds in autumn, the blood circulation of human skin and mucous membranes is poor. If you eat less fresh vegetables, the body's intake of vitamin B2 and vitamin A will be insufficient, and the skin and mucous membranes will become dry and cracked.

In order to moisten their lips, some children like to lick them with their tongues. In fact, this is a bad habit, because licking lips can only bring temporary moisture. When the moisture on the lips evaporates, it will take away more moisture from inside the lips, causing your lips to fall into a vicious cycle of "dry - lick - drier - lick again". As a result, the more you lick, the more painful it becomes, and the more cracked your lips become. What's more, saliva contains substances such as amylase. When the wind blows, the water evaporates, taking away the heat and making the temperature of the lips lower. The amylase then sticks to the lips, causing the deep connective tissue to contract and the lip mucosa to wrinkle, making the lips drier. In severe cases, it may cause infection, swelling and pain.

To prevent and treat chapped lips, it is mainly important to eat more fresh vegetables, such as bean sprouts, rapeseed, Chinese cabbage, white radish, etc. Wear a mask as much as possible to keep the lips warm and moist. You can also apply some oils, such as facial oil, sesame oil or other cooking oils, or honey or frostbite cream. If you feel your lips are chapped, don't lick them all the time, as this will accelerate the occurrence of chapped lips. The most important principle of treatment is to adjust your diet.

What's wrong with children's dry lips? It is very common for children to have dry lips in autumn and winter. Don't worry too much. You can use some lip balm for your child appropriately, and let your child eat more fresh fruits and vegetables to supplement the vitamins needed by the human body. In addition, let your child drink more water and don't let your child lick his lips all the time.
