What Are the Common Causes of Flaky Ear Skin?

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, and the role of the natural moisturizing factors contained in the stratum corneum, such as amino acids, lactates and sugars, the stratum corneum maintains a certain content. Amount of water to keep the skin moist. The appearance of the skin is related to the moisture content of the stratum corneum. Normal skin stratum corneum usually contains 10% -30% moisture to maintain the softness and elasticity of the skin. However, as the age increases, the moisture content of the stratum corneum of the skin will gradually decrease, and when the moisture content of the stratum corneum of the skin is less than 10%, the skin will appear dry, tight, rough and desquamated.
So what are the reasons that cause skin moisture loss, dry skin and tarnishing? In general, the internal and external conditions that cause the skin's natural moisturizing structure to lose balance are:
● With the aging of the skin, its moisturizing effect and barrier function gradually weaken, and the content of natural moisturizing factors decreases;
● Dry and cold climate, low humidity, such as autumn and winter;
● Some skin lesions, such as psoriasis, ichthyosis, etc .;
● Environmental and chemical factors, such as laundry detergent, soap, dishwashing detergent and other organic solvents, as well as long-term air-conditioning environment;
● Eating and sleeping habits, such as partial eclipse, low drinking water, insomnia, etc .;
