A young girl gets caught in a heavy spring downpour. Why doesn’t her skin get soggy?

The skin is covered by a cutaneous membrane, which forms a protective, water-resistant barrier. Rain can wet the skin’s surface, but it does not soak through and make the skin tissue soggy. Sweating and the body’s serous or synovial membranes do not explain this protection, so the correct choice is that cutaneous membranes make the skin waterproof.
