The red area around human lips is called "lip red edge", and its wettability is maintained by local abundant capillaries and a small amount of underdeveloped sebaceous glands. Due to the low humidity and windy sand in autumn, the blood circulation of human skin and mucosa is poor. If you eat less fresh vegetables and have insufficient intake of vitamin B2 and vitamin A, it will dry and crack.
In order to moisten lips, some people like to lick their lips with their tongues. In fact, this is a bad habit, because licking your lips can only bring temporary wetness. When the water in these lips evaporates, it will take away more water inside the lips, so that your lips will fall into a vicious circle of "dry-lick-dry-lick again", and the result will be more painful and cracked. In addition, saliva also contains amylase and other substances. When the wind blows, the water evaporates and takes away the heat, which lowers the temperature of the lips. Amylase sticks to the lips, which will cause the deep connective tissue to contract and wrinkle the lip mucosa, thus drying more severely. In severe cases, it will be infected and swollen, causing pain.
1. Use lipstick. In winter, both men and women should take good care of their lips in order to spend the cold winter healthily.
2. Take B vitamins and eat more fresh vegetables.
3. Replenish water. Adequate drinking water is of great help to the balance of human functions.
4. lick your lips less. Short-term humidification will make the lip mucosa wrinkle, aggravate chapping, and in severe cases, secondary infection and swelling will occur.
5. Moisturize with oil. People can find flour oil, sesame oil or other edible oil (honey or chilblain cream can also be used) on their lips, which can play a very good moisturizing role, sometimes even better than lip balm.
