　　Third, the temperature drops

　　In the cold winter, the secretion of sebum and sweat will decrease rapidly. However, because the air is too dry, the water in the skin gradually evaporates, the surface of the skin becomes rougher, and the resistance will be weakened.

　　4. Lack of sleep and fatigue

　　Lack of sleep combined with fatigue will cause considerable damage to the body and worsen blood circulation. when healthy When the balance is lost, the skin will lose vitality and become prone to dryness and roughness.

　　5. Weight loss and partial eclipse

　　Extreme weight loss and a picky diet can also cause the skin to become dry. When flat skin cannot get sufficient nutrients, it will lose elasticity and moisture, making the skin dry and fragile. Dry skin is also called xeroderma.

　　6. Other reasons

　　4 major causes of dry skin in late summer and early autumn

　　Dry skin in this season is different from dry and itchy skin in autumn and winter. As long as you avoid several factors that make your skin dry, your skin will quickly return to its original suppleness.

　　Cause of dryness 1: air conditioning

　　Although it is the beginning of autumn, the temperature when the sun is shining is no lower than in summer. The cold air from the air conditioner will dry out the indoor air, and the outside humidity is not as high as in summer. Part of the moisture in the skin will be taken away. If ignored, fine wrinkles will easily appear.

　　Drying trigger two: UV rays

　　As the weather becomes clearer, the ultraviolet rays in the sun will cause trouble for the skin without being blocked by thick clouds.

　　Cause 3 of dryness: excessive bathing

　　When the temperature is high in summer, people like to take one or two baths a day, and some people even take more baths. After climate change, the sweat and oil secreted by the skin will gradually decrease. Taking too many baths will easily wash away the cuticle that automatically sheds and the dirt mixed with sweat, which reduces the protection of the skin by these substances. The water in the cells is more likely to evaporate, causing the skin to become dry.

　　Dryness trigger four: summer skin care products

　　The skin care products used in summer emphasize refreshing, but these skin care products are a bit "out of date" in late summer and early autumn, and their ability to moisturize and lock water is obviously not up to standard, so it is best to start using some moisturizing skin care products to reduce water loss.

　　Counting methods one by one

　　The key to having delicate, hydrated skin lies in the moisture content of your skin. Skin includes epidermis, dermis and subcutaneous tissue. There is a stratum corneum on the outermost side of the epidermis, and the sebum film on the surface prevents moisture loss from the skin. There is also an intercellular lipid inside the stratum corneum that maintains moisture in the skin. When the skin's metabolism becomes sluggish, the sebum produced by the sebum membrane will gradually decrease.
