Found this on the web, makes sense.











';Dr. Norman Goldstein, a professor of dermatology at the University of Hawai'i John A. Burns School of Medicine. ';Goldstein has no trouble fielding this question. He calls the phenomenon 'super-hydration.' Our skin cells absorb a little bit of water when we soak too long in the tub, he says. And because the skin on our palms and the bottoms of our fingers and feet are thicker than other parts of our skin, they swell more than the rest of us. Because this swelling layer of skin is connected underneath to tissue that does not swell, the skin buckles. Hence, wrinkled fingers and toes.';Why does our skin ';prune up'; in the bath/shower?
The outermost layer of the skin swells when it absorbs water. It is tightly attached to the skin underneath, so it compensates for the increased area by wrinkling.
Look up hypotonic and hypertonic solutions.
i often wonder that too! lmao :)
because the palms of your hands and the bottoms of your feet arent waterproof like the rest of our skin, and the skin absorbs the water and becomes wrinkled. its really weird!
