Physicist here. One time in our course of biophysics they told us they told us that the molecules that form our skin tissue are incredibly smart, in the sense that as soon as water touches the surface of the skin, what is a little underneath reacts to it. And fills our skin pores with natural oils that are hydrophobic, so watee doesn’t get into our skin
