The United States "Chicago Tribune" once pointed out that the alcohol content of hand sanitizer should exceed 60%, otherwise the sterilization and disinfection effect is not ideal. People can't help worrying: Will washing your hands with this liquid soap damage your skin? Li Guangrui, director of the Department of Dermatology at Wangjing Hospital of the Chinese Academy of Chinese Medical Sciences, pointed out that this alcohol-based hand sanitizer generally does not harm the skin, and at most it is a little irritating to the skin. Just apply hand cream after washing your hands to solve this problem.
