The outer layer (epidermis) produces an oily substance called sebum, which prevent water absorption. However, after long periods of time in a swimming pool, shower, or bathtub, much of the sebum is washed off and your outer layer of skin starts to absorb water. As it absorbs water it swells. other theory is when hands are immersed in water it seems that the nerve fibers are triggered to “shrink” which then pulls the skin structures downwards to produce wrinkling. Studies on patients with loss of nerve function in their hands or fingers exhibit no or slight wrinkling when immersed in water.
