In winter, the cold weather, the skin is not easy to take care of than other seasons, the skin is more prone to lack of moisture and dry peeling, causing itching, how to make the skin crystal clear and watery in this season? 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 role of natural moisturizing factors contained in the stratum corneum, i.e. amino acids, lactates and sugars, the stratum corneum maintains a certain water content to maintain the moist skin. The appearance of the skin is related to the moisture content of the stratum corneum, which normally contains 10%-30% water to maintain the softness and elasticity of the skin. But as we age, the moisture content of the stratum corneum will gradually decrease, and when the moisture content of the stratum corneum is below 10%, the skin will appear dry, taut, rough and flaky. When the northwest wind blows, human skin will also be reduced due to the lower temperature, both explicit sweating and implicit sweating are greatly reduced, and the secretion of sebaceous glands, the lubricant of human skin, is also greatly reduced, dry skin is related to the loss of water in the skin, and the lack of water in the skin is related to the natural sebum of the skin, the lipid on the surface of the skin is like an outer coat, which prevents the evaporation of water from the skin and keeps the skin moist, the skin of the elderly The thinning of the skin of the elderly, the surface of the lipid also reduces, the skin naturally appears dry, the cold wind in winter can increase the loss of moisture, further disturbing the epidermal lipid balance, so dryness is inevitable, this year’s winter rainfall is particularly low, the weather is dry, the human skin is more prone to dryness. So housing to maintain a certain humidity, you can put some green potted plants, or put a pot of water to increase air humidity. Bathing water temperature at about 32 ° C, should not rub, should not use too much soap, should avoid the use of washing power too strong soap and detergent, these things will wash away the natural protective oils made by the human body, avoid scratching, after the bath can be applied to the whole body with emollients to keep the skin moisturized, it is recommended to apply moisturizing cream or moisturizing lotion daily. The diet should be rich in vitamin A foods, such as carrots, cabbage, etc., and less coffee, cola, spicy and acidic food.
