Hypodermis (Subcutis)

The subcutis is joined to the bottom of the dermis and is the deepest layer of skin. Lipocytes located within the subcutis make lipids for the subcutaneous tissue. The subcutis functions as a cushion for muscles, bones, and internal organs and can also act as an insulator or energy source when needed.
