The epidermis sits above the dermis, the middle layer that contains connective tissue, hair follicles, and sweat glands that regulate the integrity and temperature of your skin. The deeper hypodermis layer, also called subcutaneous tissue, is made up of fat and even more connective tissue.
Overview. The epidermis is the top layer of your skin. What is the epidermis layer of skin? Your skin has three main layers, and the epidermis (ep-uh-derm-us) is the outermost layer in your body. The other two layers of skin are the dermis and hypodermis.

Epidermis. The epidermis is the outermost layer of the skin, forming the body’s primary protective barrier against environmental factors. It is composed mainly of keratinocytes, cells that produce keratin, a protein that strengthens the skin and helps in its protective function. The epidermis is a thin, avascular (without blood vessels) layer ...
The Epidermis. The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. It does not have any blood vessels within it (i.e., it is avascular).
The epidermis has a complex structure designed to protect from the environment. It has an undulating surface with cross-crossing ridges and valleys, with invaginations due to follicles and sweat duct ostia.
