How effective is the antibacterial hand sanitizer?

In order to unravel the mystery of the effect of antibacterial hand sanitizers, we have to discuss its ingredients. The non-drug compounds that are usually added to hand sanitizers have disinfection and bacteriostatic effects, but this bacteriostatic effect is only manifested in the fact that they are in Efficacy in inhibiting bacterial growth in the laboratory. ​In terms of disease prevention, there is currently no evidence that toiletries marked with 'bacteriostatic/antibacterial' effects are better than ordinary soap and water. In this case, do we still need to use antibacterial hand sanitizers? Can it be? What about bringing extra protection to us and our families? First of all, for the evaluation of the antibacterial effect, any antibacterial statement that the few people want to say without talking about the concentration is a hooligan. This is because the disinfectant or bacteriostatic agent has a minimum inhibitory concentration that can exert its effect, below this limit, it no longer has bacteriostatic effect. That is to say, people wash their hands with tap water. If the flushing time is longer and the flushing effect is more thorough, then whether the residual bacteriostatic agent on the skin has an effect will vary from person to person. Secondly, we should correctly understand the body's own immune system. The human hand skin is a natural barrier. It not only maintains the natural balance of various bacteria on the hand, but also resists a large number of pathogenic bacteria for the human body. If we use antibacterial Hand sanitizer affects the living environment of normal flora, which is likely to lead to dysbiosis, which is not conducive to the exercise of the human immune system. Third, the study found that even if you use soap without antibacterial ingredients, as long as you go through a standardized and careful handwashing process, most of the attached bacterial colonies can be eliminated. The attachment and spread of the disease shows that 'how to wash your hands' is much more important than 'what to wash your hands with'.
