If you could total up the number of cells that you’re losing, it’s about 40,000 skin cells a minute that fall off of you.
    Now water can get into that layer of dead skin on your fingers and it makes the cells swell up a bit. They swell up, they press into each other, and as a result, they push each other out of the way, and they get thrown up into all these ridges and folds After you get out of the water you dry out again, that extra moisture that’s got into the cells comes back out, the cells flatten out again, and they go back to their normal shape, and that’s why you go wrinkly in the bath.

  2. This is only a temporary skin condition when you get wrinkles in your palms or your feet after exposing to water for a long time. The recent studies explain this situation with “vasoconstriction” hypothesis. Simply whay they suggest is, water diffuses into your hands through very small pores on your skin (like sweat ducts) and causes wrinkling by altering the balance of chemicals in the skin (well it will be diluted with water). This situation mainly affects the membranes of neurons on your skin making them fire electric signals to brain more rapidly as a result your blood vessels constrict and the amount of fluid under your skin decreases. This decrease in fluid also cause a decrease in tension so you get wrinkly skin …
