Lizards have relatively thick skin with ectodermal scales formed by folding of the epidermis and outer dermal layers. Lizards undergo reguler periods of shedding (ecdysis) during which the skin comes off in large patches. Frequency depends on the species, temperature, humidity, state of nutrition, and rate of growth. Presence of wounds or skin infections maybe increase the frequency of shed cycles.
