There are three layers of the skin.

Epidermis – the surface epithelium of the skin, overlying the dermis. It is the top layer of skin that does not have blood vessels. Its function is to serve as the protector and provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation that may cause damage. The epidermis produce keratin making the skin waterproof. It also has melanocyte which makes melanin which is responsible to give the skin color. Merkel cells which in involved with the touch reception and Langerhans cell which help the immune system fight off foreign bodies. The skin shed millions of dead keratinocytes every day.

The middle layer is the dermis it is the thick layer of living tissue below the epidermis which forms the true skin, containing blood capillaries, nerve endings, sweat glands, hair follicles, and other structures. They dermis has two layers the papillary layer that has loose connective tissue and the other is the reticular layer that has the dense connective tissue. The dermis has a structure for hair it also provides a site for the endings of nerves and blood vessels. The dermis houses the lymph vessels that help prevent infections. The sweat glands and oil gland are also housed in the de dermis and that is where hair follicles are attached.

The final layer of the skin is the hypodermis is the bottom layer of skin in your body. It has many important functions, including storing energy, connecting the dermis layer of your skin to your muscles and bones, insulating your body and protecting your body from harm. As you age, your hypodermis decreases in size, and your skin starts to sag. This part of the skin also composed of connective tissue called adipose tissue this store excess energy bas fat. This lay of skin also houses lymph vessels blod vessel hair follicles and nerves.
