Why is our hand,s skin shrinking when we wash clthes for a very long time?
Sebum is found on the outermost layer of skin. Sebum moistens, or lubricates  and protects your skin. It also makes your skin a bit waterproof.But staying in water for a long time washes away the sebum. Then, the water can penetrate the outer layer of your skin. This causes your skin to become waterlogged.When we wash the clothes, the water around the fingers or hand behaves like hypertonic solution and water starts coming out from finger(cell) to out side region causing the fingers to shrink.
