We shed a million skin cells a day
The process called Apoptosis, is when the body routinely kills off and replaces damaged or used-up cells, sloughing off dead skin, at a rate of perhaps a million cells a day.
We lose between 30,000 and 40,000 skin cells every hour.
In one year, you’ll shed more than 8 pounds (3.6 kilograms) of dead skin.
Most household dust is made of dead skin cells, of which a lot is devoured by dust mites.
