What will happen if do not have skin?

Answer 1

you have no hair growing out, and you can't sweat. in this case, you need to be in a cool area and avoid being in the sun for too long or else you will overheat to the point of heat stroke. not a good idea.

Answer 2

One way to think about your skin is as a container: without it all your organs would fall out and your skeleton would collapse.
