Filled Under:

Why our fingers begin to wrinkle in water

Water tends to wash away the oily substance that protects your skin.  When this occurs, a certain type of dead cell on your skin will absorb the water causing the cells to swell up, but the layer underneath doesn't.  So the swelling, in addition to the places the skin is connected underneath to the non-swelled layer, causes your finger tips to look all wrinkly.
