What causes cleft lip? Three reasons are most prominent

Cracked lips are most common in autumn and winter. During these seasons, due to the abnormally dry weather, people's lips will also crack due to lack of water. So, what causes chapped lips?

Dry weather and lack of water

Seasonality is common, especially in the dry seasons of fall and winter. The dry climate can easily cause chapped lips. The lips are mucous membranes without sweat glands or oil secretion function, so in the dry season, the lips will easily become dry. At this time, many people will lick or bite their lips with their tongues, but the moisture will quickly evaporate, taking away the already scarce moisture on the lips, causing the lips to become drier and the more they lick their lips, a vicious cycle of becoming drier and cracked, and peeling lips.

Vitamin deficiency in the body

Chapped lips are related to the fact that people eat less fresh vegetables and do not take in enough B vitamins in their daily life. 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 poor blood circulation in the human skin and mucous membranes in autumn and winter, if you eat less fresh vegetables, the body's intake of vitamin B2 and vitamin A will be insufficient, causing the skin to dry and crack.
