What is the reason for chapped lips? Drinking water doesn't work. It still hurts.
Step 1 The weather is dry and lacks moisture.
Common seasonality, especially dry season in autumn and winter. The climate is dry, and it is easy to chapped lips. Lips are mucous membranes, no sweat glands and no oil secretion function. So in the dry season, lips are easy to dry. At this time, many people lick or bite their lips with their tongues, but they are quickly evaporated, and at the same time, they take away the water that is scarce on their lips, which leads to a vicious circle of dry lips and peeling lips.
Criteria for judging: chapped lips caused by insufficient water, manifested as dead skin accumulation on lips or corners of the mouth.
The body lacks vitamins.
Judging standard: If the corners of the mouth start to crack and there is white secretion at the corners of the mouth, it is a phenomenon of vitamin deficiency, so attention should be paid to internal conditioning.
Chapped lips are related to eating less fresh vegetables and insufficient intake of B vitamins in people's daily life. 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 poor blood circulation of human skin and mucous membrane in autumn and winter, if you eat less fresh vegetables and have insufficient intake of vitamin B2 and vitamin A, it will crack.
cheilitis
If you always feel chapped lips, it may be caused by vitamin B2 deficiency and indigestion, or it may be chronic cheilitis. You'd better ask a doctor for help in diagnosis.
Panniculitis often occurs in young people, and some bad habits are the inducement. If the lips are dry, they will lick or bite, leading to increased pain, bleeding lips and infection. The wound is difficult to heal, and it will recur, forming a vicious circle, which will develop into chronic cheilitis after a few days' delay. Diseases in the mouth can also lead to chapped lips, so pay attention to oral cleanliness. If chapped lips and scabs do not heal for a long time, you should go to the hospital for symptomatic treatment in time.
Physical factors
People who are allergic to some cosmetics or sunshine, people who are prone to get angry due to excessive mood swings, and the osmotic pressure of tissue fluid in human body caused by certain diseases (diabetes) decreases, resulting in excessive drainage of tissue fluid and insufficient water, and spicy stimulation of tobacco and alcohol is easy to cause chapped lips.
