How come only your fingers and toes get prune in the shower or taking hot bath and nothing else does?

Answer 1

Because there is connective tissue underneath the surface of the skin on your fingers and toes that anchor the skin, while some portions of the skin swells from the water.

It merely wrinkles up, like a prune."
