Learn how regenerative properties of the skin helps to protect the human body from the external environment — human skin Human skin, whose cells are generated continuously by the body, serves as a protective barrier between the inside of the human body and the environment.

The subcutis, also known as the subcutaneous layer, cushions and insulates the body primarily through its composition of adipose tissue.1

This layer consists of specialized fat cells called adipose cells that are organized within a structural network of fibers. The cushioning effect is achieved because these fat deposits act as soft, elastic padding beneath the skin, protecting underlying structures.21

Regarding insulation, the adipose tissue helps conserve body heat. This is largely due to the properties of white adipose tissue, which is the most common type found in this layer. By serving as a thermal barrier, this tissue helps the body maintain its internal temperature. While brown adipose tissue is also capable of generating heat through thermogenesis, its primary role in humans is more prominent in infants, whereas the white adipose tissue in the subcutis serves as the primary structural and insulative layer for the body.12
