      Your skin is coated with an oil called sebum, which makes it waterproof. However, if you are in the bath for a while the sebum gets washed off, and water can get in your skin, making it go waterlogged. It’s thought that your fingers then go wrinkly as an automatic response, so that you can grip better.
