The skin is an organ that has an important role in our body as it helps us maintain several bodily functions, each of which plays a vital role in our overall well being.

Skin or integument is a layer of tissue that covers the outer surfaces of the body. It protects the body internally and externally and also absorbs and stores nutrients. It also produces sweat to cool down body temperature and other functions. It is a very important organ of the human body. It consists of three kinds of skin: epidermis, dermis, and subcutaneous tissue. Concepts of skin are found in many fields, especially in dermatology. Dermatologists are specialists who deal with diseases affecting the skin. The term epidermis means outer or outermost layer. It is composed of cells that are arranged in layers, each one having a specific function. Its functions are protection against infection, adhesion to the body surface, shedding old cells along with new ones, production of keratin which is the main component for strengthening hair roots and nails, absorption of Vitamin D3 from sunlight which helps in calcium absorption through bones and teeth, etc.
