What Causes Wrinkly Fingers? | BYJU'S Fun Facts

Go for a swim, take a long shower or wash the dishes, and you’ll notice one common thing. The skin at the tip of your fingers and toes get wrinkly and pruney. Why is it that our perfectly normal skin turns into a raisin? Is it because our skin soaks up water and transforms into one? Or is there an entirely different explanation to this pruney and wrinkly phenomenon?

In this BYJU’S Fun Facts video, we journey through the structure of our skin to answer this puzzling question. We visit the epidermis, dermis and underlying blood vessels to understand their connection with our nervous system, and how they collectively work to wrinkle the skin at the tip of our fingers and toes. We also cover why this natural behaviour of the human body is a necessary part of living.
