I get how soap works by breaking down outer layers of cells, especially in viruses and bacteria, which is how it protects us (correct me if I’m wrong). My question is why does everyone, including surgeons scrubbing in for surgery, massage the soap around their hands and arms? Couldn’t we just apply the soap, wait 20 seconds, then rinse it off? Maybe it’s a surface area thing, making sure soap is applied everywhere?

Soap helps to breakup the biofilm and oils built up on our hands for the water to wash it away. There’s also actually a bit of a pushback against antibacterial soap, even in the medical field, where it’s only required for critical care areas.
