Introduction
Skin is considered to be the largest organ in the body of an organism. It is the outer layer that covers the entire body and protects the inner organs from microbes and infectious agents. Skin also plays a major role in the maintenance of the internal body temperature.
Skin is further divided into three integumentary layers, namely the epidermis, dermis and the hypodermis. The epidermis is the outermost layer and works as a barrier. The dermis consists of connective tissue and the hypodermis consists of connective tissue and fat molecules.
