Because it is constantly producing more skin cells
We tend to just call it a shed skin. The technical term for the process of shedding is Ecdysis - or moulting - or sloughing.
In biology, moulting (or molting,[1] also known as shedding or for some species, ecdysis) signifies the manner in which an animal routinely casts off a part of its body (often but not always an outer layer or covering), either at specific times of year, or at specific points in its life-cycle. Moulting can involve the epidermis (skin), hair or fur, or other external layer. In some species, other body parts may be shed, for example, wings in some insects. Examples include old feathers in birds, old hairs in mammals (especially dogs and other canidae), old skin in reptiles, and the entire exoskeleton in arthropods. .
