Hand sanitizer and soap are not primarily disinfecting for neoconjunctivitis, but rather cleansing. Soap and hand sanitizer work similarly, differing only in form, being solid and liquid, but they achieve the same practical effect, both washing away the injured dirt as quickly as possible. Therefore, there is no difference between hand sanitizer and soap. In fact, soap includes hand sanitizer, and some people call hand sanitizer liquid soap. In this case there is no need to distinguish between soap and hand sanitizer. If you must distinguish between the issues that need attention are: 1, the use of soap may lead to cross between users; 2, such as hand sanitizer placed for a long time, which may grow more bacteria. But its the same cleaning effect of both, as long as the soap or use hand sanitizer to clean to each part of the hand, it can play a very good cleaning effect. Content source: Dr. Yau Lai
