Often take a bath and rub your skin hard, will it make your skin rough?

Yes Because excessive rubbing in the bath will damage the protective layer of the skin and reduce the resistance of the skin, because there is a layer of keratinocytes on the surface of the skin, commonly known as "dead skin", with a thickness of only 0. 1 mm, which is weakly acidic and can block pathogens and harmful rays. It is the natural defense line of the human body. The update speed of this dead skin is relatively slow, and it takes more than ten days at the earliest, while it takes more than one hundred days on the inner side of the upper arm. Rubbing hard in the bath will destroy this line of defense, which will easily cause skin infection, folliculitis, boils and even septicemia. Therefore, it is not advisable to wipe the skin when taking a bath, let alone wipe the skin with a dry towel or loofah tendon.
