- The body's bottom layer of skin is called the hypodermis. It serves a variety of crucial roles, including energy storage, tying the muscles and bones beneath the skin's dermis layer to one another, keeping the body warm in a variety of temperatures, and guarding against injury-related harm. 
- The hypodermis shrinks with ageing, the skin begins to sag, and the skin is more susceptible to damage and injury.
