What is the reason for body dandruff

Most people are prone to dandruff in winter. This is actually caused by drier skin. In winter, the skin easily loses moisture and becomes particularly dry. This is when the skin peels and turns into dandruff on the skin, but it is not very serious. If it is particularly serious, it may be due to other reasons, and it is not just a problem of dry skin. So what is the principle behind dandruff on the body?

Dryness: Winter Skin's Big Enemy

The skin is divided into epidermis, dermis and subcutaneous fat. The outermost layer of the epidermis is the stratum corneum. Due to the water absorption and barrier function of the stratum corneum itself, as well as the effects of natural moisturizing factors contained in the stratum corneum, namely amino acids, lactate and sugars, the stratum corneum maintains a certain water content and keeps the skin moist. The appearance of the skin is related to the water content of the stratum corneum. Normal skin stratum corneum usually contains 10%-30% water to maintain the softness and elasticity of the skin. However, as we age, the moisture content of the skin's stratum corneum gradually decreases. When the moisture content of the skin's stratum corneum is less than 10%, the skin will appear dry, tight, rough and flaky.

So what are the reasons that cause skin moisture loss, leading to dry skin and loss of luster? Generally speaking, the internal and external conditions that cause the skin's natural moisturizing structure to lose balance are:

●As we age, our skin ages, its moisturizing and barrier functions gradually weaken, and the content of natural moisturizing factors decreases;

●Dry and cold climates with low humidity, such as autumn and winter;

● Certain skin lesions, such as psoriasis, ichthyosis, etc.;

● Environmental and chemical factors, such as detergents such as washing powder, soap, dishwashing liquid, organic solvents such as alcohol, and prolonged air-conditioning environment;

●Eating and sleeping habits, such as partiality, drinking less water, insomnia, etc.;

●Dry skin.
