Who’s skin is made up of dead cells and as it grows, it changes to new?

Reptiles (or amphibians) are living organisms whose skin consists of two layers. The bottom layer of delicate cells is unable to maintain a constant body temperature and skin moisture. The top layer of the skin of a reptile consists of keratinized cells, which are scales that fit tightly to each other. This structure allows you to keep warm and moist skin, but the structure of the scales is very tough and unable to grow with the body, therefore, approximately once a year, reptiles change their “skin”.
