Subcutis Layer

Last updated: May 5th, 2025

The subcutis layer is one of three integrated layers of the skin. It is joined to the bottom of the dermis (the second layer) and is the deepest layer of the skin. It contains lipocytes, which produce lipids for the subcutaneous tissue to make a fatty layer that cushions muscles, bones and inner organs against shocks, and acts as an insulator and source of energy during lean times.
