Hypodermis (Superficial Fascia)

The hypodermis, or subcutaneous layer of the skin, is a deeper continuation of the dermis. It consists of loose connective tissue and adipose cells forming a layer of variable thickness depending on its location in the body.

The hypodermis facilitates mobility of the skin, and the adipose tissue contributes to thermal insulation and storage of metabolic energy and acts as a shock absorber. The hypodermis contains muscles in the head and neck (for example, platysma). No adipose tissue is found in the subcutaneous portion of the eyelids, clitoris, or penis.
