Knowledge Bank Why (and How) Your Skin Wrinkles Underwater?? our skin is made of two layers: the epidermis (the layer you see) and the dermis (the layer underneath that contains blood vessels). When your hands and/or feet have been underwater for a long time, your nervous system tells the blood vessels in your dermis to constrict. This reduces the volume of the dermis, which in turn reduces the tension with which the epidermis is stretched. As a result, the epidermis “relaxes,” forming wrinkles. Interesting.. hmmm.. And why it happens? thats more interesting!! because the wrinkles help to increase the grip or friction to handle things underwater
