Facial volume loss is caused primarily by the loss of collagen and elasin in the skin due to the effects of ultraviolet light and time. When the face loses these critical supports for the skin, the cheeks descend from their usual high position in the face near the eyes, sagging to a lower position that makes the face appear more square. Dermal fillers can be an excellent treatment option to reverse these changes, restoring the youthful heart-shaped facial contour.
