What do you mean by rubbing mud?

The surface of human skin is metabolized every day. The outermost layer is stratum corneum, which is a layer of dead cells to protect the skin. There are sebaceous glands and sweat glands in the skin, which secrete oil and sweat to the surface every day.

the skin is exposed to wind and rain every day, and it is inevitable that there is no dust attached. To sum up, the mud rubbed out every day consists of dead cells in the stratum corneum, sweat, grease and dust in the air. Be careful not to rub the mud too thoroughly, because this layer of mud can protect the user and prevent too much moisture from entering the body.

Precautions:

1. It is very important to take a bath according to the skin oil activity. Generally speaking, people with oily skin, regular exercise and strong endocrine can take a bath twice a week.

2. Frequent rubbing is not recommended: Try not to rub the bath frequently in your life, because excessive rubbing will actually cause sebum and stratum corneum on the skin surface to be easily damaged.

3. The skin's sensitivity is declining, which will make the skin drier and drier, and even cause allergic reaction when the water loss is serious.
