What causes the peeling of the mouth

Winter, another year dry season, every time this time, there are always a lot of girls will have dry and cracked lips peeling phenomenon. Perhaps you have the same question as I do, why do your lips dry and peel or even crack and bleed in winter?

Dry weather and lack of water

The weather is dry in autumn and winter, the air humidity is low, sandy, lips not only do not get the moisture in the air, the surface of the moisture will be dried by the wind, making the surface of the lips significantly reduced moisture. Coupled with the colder weather, the blood circulation and metabolism of the lip area slowed down, naturally prone to dry and cracked lips peeling phenomenon.

Lips do not have sweat glands

The lip area is a mucous membrane, no mature sweat glands, no oil secretion function, so the lips can neither moisten the surface skin through their own secretion of sweat, nor help lock water through the secretion of oil, in the dry autumn and winter season, it is easy to dry cracking or peeling bleeding.

Lick your mouth

When the lips are dry or cracked and peeling, people will subconsciously lick their mouth or bite the dead skin on the lips. Saliva can temporarily moisten the lips, but after the evaporation of saliva water will leave proteins such as amylase, sticky lips will trigger the contraction of deep connective tissue, making the lip mucosa wrinkled, leading to more severe dry lips, and even cause infection, swelling, also known as "tongue lick dermatitis" in medicine.

Vitamin deficiency

Dry and cracked lips may be a lack of B vitamins, vitamin A, vitamin C, there is a red area around the lips "lip edge", mainly by the surrounding rich capillaries and a small number of underdeveloped sebaceous glands to moisten, winter if the intake of vitamins is not enough, it is easy to dry and cracked. Vitamin B2 has the effect of helping to repair tissue wounds, and when the body is deficient in vitamin B2, the lips will appear cracked or inflamed. Vitamin A has the role of keeping the mucous membrane moist and intact, and lack of vitamin A can easily cause dry and peeling lips. Vitamin C can promote the healing of tissue wounds and help repair cracked and bleeding lips.

Using improper lip products

(1) Use of non-depigmented lip balm Non-removable lip balms contain volatile ingredients and most of them do not contain oil and have poor moisturizing effect. (2) Use of poor quality lip care products Poor quality lip balm contains a lot of harmful ingredients, not only can not play the effect of lip moisturizing and lip care, but also damage the mucous membrane on the lips. (3) Excessive use of lipstick Lipstick contains more chemical ingredients, less moisture and oil content, when the lips are dry, the use of lipstick will aggravate the symptoms of dry and cracked lips peeling.
