The epidermis is the outer, thinnest layer of the skin. It is composed of dead cells that face the extracellular environment and layers of additional cells underneath. One of the main types of cells in the epidermis is keratinocytes, which are dead at functional maturity and help form a barrier of the skin. The epidermis also contains melanocytes, which produce melanin for protection from ultraviolet rays from the Sun. There are also sensory cells and immune cells in the epidermis.
The dermis is the thick, middle layer of the skin. It contains two main layers, the papillary and reticular layers. The papillary layer is the thin upper layer made of loose connective tissue. The reticular layer is the deeper, denser layer filled with collagen fibers. Within the dermis are the sweat glands, muscles, hair follicles, nerves, and blood vessels.
The deepest layer of the skin is the hypodermis. The hypodermis is also called the subcutaneous fascia. It houses the adipose tissue of the skin and helps regulate temperature in the body. The hypodermis can also contain blood vessels and nerve endings as well.
