The skin is the largest organ of the body. Scientists estimate that one square inch of human skin contains about 20 million cells.
Most people gradually lose an entire outer layer of skin cells every month.
We shed dead skin cells every day. Other parts are thick and firm, such as the soles of the feet. To take good care of your skin, wash it regularly, protect it from the sun, and use moisturizer when it's dry. What you eat does not cause pimples. The skin makes more melanin when it's exposed to UV light.
