Our faces change shape with age, as we naturally lose subcutaneous fat and bones thin leading to volume loss.
Areas prone to this including the cheeks and temples which become hollow, skin appear to sag and lines around the lower face become more pronounced. Loss of fat pads in the central face can lead to a gaunt appearance.
From the mid -20's, natural levels of collagen and hyaluronic acid decline so skin becomes less plump with more laxity. Hyaluronic acid is a naturally occurring sugar found in skin and tissues that attracts water.
Dermal fillers contain cross-linked hyaluronic acid to help replace volume loss in areas such as the cheeks, and temples.
