There are approximately 6 million cells per square centimeter of skin.  Of course, these cells vary in function.  The skin is made up of nerve fibers, pain sensors, blood vessels, sweat glands, and temperature sensors among others.  Each of these involves different types of cells, from neurons to blood cells.
