The outer layer of skin is called the epidermis. New cells are constantly being formed and migrate to the surface over a period of 1-2 months where they die and harden. Here they form a protective layer called the horny layer. This is constantly being worn away by friction. The protective layer is normally worn away but is constantly being regenerated. The problem arises where the rate of damage or wearing to this layer exceeds the rate of repair.
