What is the dermal subcutaneous junction?

The dermal-subcutaneous junction is the boundary between the dermis and the subcutaneous layer (hypodermis). It is also known as the fascia superficialis. The dermis is the innermost layer of the skin and is composed of connective tissue, blood vessels, nerves, and glands. The subcutaneous layer is the outermost layer of the skin and is composed of fat cells, connective tissue, and blood vessels. The dermal-subcutaneous junction serves as a barrier between the two layers and provides structural support to the skin. It also contains the superficial fascia, which is a thin layer of connective tissue that separates the dermis from the subcutaneous layer.
