There are two main skin layers:
The bottom layer shown in the picture (hypodermis) is not really part of the skin. It is a layer of connective tissue, fat cells, blood vessels, and nerves. The hypodermis is the connection between the skin and the structures under it, such as muscles.
Skin depth varies depending on location. It is thin on the neck, thick on the soles of the feet. Connective tissue, fat, muscles, and muscle covering (fascia) lie below the skin.
