Some of people were scared of their skins after bathing.

  Why does the skin on the extremities wrinkle after a bath? and why only extremities? Despite it's appearance , your skin isn't shrivelling  after you bath. Actually , it is expanding. The skin on the fingers, palms , toes and soles wrinkles only after it is saturated with water ( a prolonged stay underwater in the swimming pool will create the same effect). The stratum corneum - the thick , dead layer of the skin that protect us from the environment and that makes the skin on our hands and feet and thicker than that on our stomachs or face- expending when it soaks up water. This expansion causes the wrinkling effect.
   So why doesn't the skin on other parts of the body also wrinkle when saturated? Actually , it does, but there is more room for the moisture to be absorbed in these less densely packed areas before it will show. When I went for National Service Training and i showed it to the doctor and he said that all trainers whose feet are submerged in soggy boots for a long period will exhibit wrinkling all over the covered area. This is cause by the newly developed skin and dead skin will removed by itself.
