Fingernails are just another type of skin, but not all nails are created equal. The nails protect the nerve-rich fingertips and tips of the toes from injury. Nails are a substructure of the outer layer of the skin and are composed mainly of keratin, a type of protein. Nails grow at the rate of about 0.05 to 1.2 millimeters per week. The nail bed is the skin on the top of which the nail grows. Healthy nail beds are pink to dark pink, which show a rich blood supply.
