Why does my skin look like a "wrinkled prune" after I take a bath?

Your skin will look like a wrinkled prune after taking a bath, because our skin is composed of layers. There is the outer layer which is basically dead skin, and that is the part of the body that is exposed to the air and everything around us. And then below that is the living layer of the skin and when you get into water that outer layer absorbs water. And, because you have two layers right next to each other, one layer is going to cause the other layer to pull and causes all these wrinkles and bumps in the skin so the longer you are in the water, the more water your outer layer will absorb and that causes the skin to wrinkle.
