The skin is our body's envelope, acting both as a protection and as a means of interacting with the outside world. Its structure is complex and divided into three layers: the epidermis, the outermost layer, the dermis, and the deepest, the hypodermis, each of which fulfils precise functions. In addition to these are the skin appendages the hair on the head, body hair, nails, sweat glands
and sebaceous glands.
