Why does water roll off a perons skin when person gets out of the water?

Answer 1

Because of the lipids that our cells contain. Our skin is water resistant, but it still soaks up water a little. but we dont get all soggy and break apart, or we dont get all heavy like a sponge when it absorbs water.

Answer 2

Water rolls off a person's skin due to the combination of surface tension and the hydrophobic nature of human skin. The outer layer of the skin, called the stratum corneum, is composed of dead skin cells and lipids that repel water, causing it to bead up and roll off the skin surface. This helps to prevent water from penetrating the skin and promotes waterproofing.
