A note from Cleveland Clinic
The hypodermis is the bottom layer of skin in your body. It has many important functions, including storing energy, connecting the dermis layer of your skin to your muscles and bones, insulating your body and protecting your body from harm. As you age, your hypodermis decreases in size, and your skin starts to sag. Dermal fillers help restore volume to your skin as your hypodermis decreases.
