Doesn’t it work because the alcohol breaks down the lipid cell membrane?

Only 70% iso will really work to kill germs. 90% evaporates before it has a chance to penetrate the cell wall. I know that’s not what you asked but it’s still a cool fact. Your skin is constantly being damaged, and repaired. It’s also covered in a layer of dead skin. The germs you want to kill are invisible, small in number. Your skin cells are in such great numbers that you can physically see it. Given enough iso over a long enough period of time you can definitely kill your skin cells
