Collagen and elastin levels in our skin tend to decline as we age, resulting in volume loss in important regions of the face such as the cheekbones, under-eye area, and cheeks. It may also make specific parts of the face appear heavier, such as the jowls and neck, causing drooping skin and altering the structure and form of our whole face. 

A typical feature of aging is the loss of facial volume, especially when combined with enlarged fat pads in the lower face and neck. Hormonal changes, environmental variables, and severe diet and activity are the three primary reasons of face volume reduction.
