As a result of frequent bathing, bathing too often, resulting in a large number of skin stratum corneum loss, stratum corneum shedding after a certain degree of damage to the granular layer of the skin as well as the spiny layer of cells, which damage the barrier function of the skin, it is easy to cause some artificial skin diseases.
