Hello: Wipe your hands often with alcohol, which may cause the skin to lose elasticity gradually because of the super penetration of alcohol. This penetration can penetrate into cells, which is caused by protein's coagulation and denaturation. Because alcohol is volatile, it takes away the heat and moisture of the skin, reduces the natural moisturizing ability and purchasing immunity of the skin, resulting in dry and rough skin, exuberant sebum secretion and large pores. The skin will age faster. Alcohol can paralyze cells, making it difficult for cells to distinguish between good and bad nutrition, thus absorbing some harmful substances to the skin, such as lead, mercury and other harmful substances, making the skin no longer healthy.
