Shedding is the normal process of skin renewal. The frequency depends upon the rapidity of growth, age, nutritional state, size and environmental factors. For most lizards, the skin sheds in patches, except for the '''alligator lizard''' which sheds in one piece.

A change in colour can be noted prior to shedding; the overall shade of the lizard gets progressively dimmer and duller around the head and limbs and grey/ white patches of skin begin to appear, progressing from head to tail. The shedding occurs on all parts of the body, including eyelids.
