Your skin is composed of several layers. The layer you can see is called the epidermis. It's composed of cells made of keratin, a hard substance that also forms your hair and nails
New keratinocytes grow at the lowest level of the epidermis, which bonds with the next layer, the dermis. The new skin cells gradually push their way to the top layer. When they reach the top, they die and are "weathered" by the environment and your daily activities. The top "dead" layer is called the stratum corneum. Eventually, the dead cells break away from the epidermis and fall off, making room for newer cells growing up from below. It takes roughly one month for new cells to get all the way to the top layer, meaning the skin you have a month from today will be completely new compared to the skin you have now.
Scientists estimate that the human body is made up of around 10 trillion cells in total. Your skin makes up about 16 percent of your body weight, which means you have roughly 1.6 trillion skin cells
Of those billions of skin cells, between 30,000 and 40,000 of them fall off every hour
Over a 24-hour period, you lose almost a million skin cells
Where do they all go? The dust that collects on your tables, TV, windowsills and on those picture frames that are so hard to get clean is made mostly from dead human skin cells. In other words, your house is filled with former bits of yourself. In one year, you'll shed more than 8 pounds (3.6 kilograms) of dead skin. It gets even grosser: Your house is also filled with trillions of microscopic life forms called dust mites that eat your old dead skin.
