I remember from my high school biology class that almost all cells are protected by a lipid bilayer. I know that soap kills germs by disintegrating this bilayer, causing the bacterium to fall apart. How come soap doesn’t do this to skin cells?
In: Biology
It does, a little. We have extra skin layers so that the effect isn’t harmful. We used to use lye as a soap ingredient, but it was a little too good at its job, what we low call harsh. Now we use milder chemicals.
