Did you know that the average person takes approximately 10,000 steps a day? This averages out to walking four times around the world and places approximately 600 metric tons of force on the soles of the feet in the course of a lifetime. That is a tremendous amount of stress and pressure on the bottoms of those important, but often neglected, appendages at the end of the legs.
The amount of pressure exerted on the feet gives a good indication that the skin on the soles must be very different than on the rest of the body.
The skin of the soles
The skin of the epidermis on the soles of the feet is much thicker; up to 1.4 mm and comprised of five distinct layers. It has to be thicker to withstand the amount of stress and pressure placed on the soles with every step. There’s more: The skin on the soles of the feet has an additional layer in the epidermis, and the skin cells are packed together in a strong, congruent membrane. The skin on the bottom of the feet also has four times more sweat glands, but does not have hair or sebaceous glands. Due to these functional features of the skin on the soles of the feet, it does not respond as readily to typical skin care techniques practiced elsewhere on the body.
