Answer: Skin cells go through more wear and tear.
The body only produces what it needs. There is also a greater limitation when it comes to space within our bodies and in organs such as the liver and kidneys. Skin cells reside on the outside of our bodies and because if this, we tend to lose more of them compared to the cells inside our bodies. The epidermis is also the largest organ on our bodies, so cells are not as limited to space when compared to other organs.
