The most common results of the loss or downward displacement of the subcutaneous fat pads in the middle of our face due to aging or genetic predispositions include a tired expression, increased under-eye circles and bags, a deepening tear trough, and increased corner-of-mouth lines. This loss of volume in the midface can be restored in the most natural way by injecting filler. Midface filler procedures take just a few minutes, do not require anesthesia, and last for at least a year.
