Zhengzhou personnel office level 3 2010-1-14 hehe, it's not human body and air. It is water. Water is formed by too many minerals, which will cause diseases to the skin in too many cases. Long Xiao Doudou asked: No, my arms are wrapped up in winter. How can there be water? Answer: In this case, I preliminarily judge that 1, your skin is dry due to lack of water. The solution is to apply shower gel or oily skin care products after taking a shower. 2. Your excessive bathing causes serious sebum loss. 3, you have a slight skin disease, mainly depends on whether you have a lot of dandruff after taking off your close-fitting clothes. If so, it is acceptable to take a bath every 3-4 days, and it usually takes about 7 days in winter according to the situation. Only in the northern region, the south decides the requirements according to the weather: I don't have it on my clothes, and I don't have it when I soak my hands in water. Besides, how can dead skin fall off easily? After a while, I wrapped my hands and didn't answer: I really can't help what you said unless you tell me your geographical environment, air humidity, temperature, diet, rest, clothes and so on.
