Riverisland, thank you for the pictures upload. You have a classic tear trough deformity which shows a sunken appearance of the area underneath the eye terminating at the junction between the bone of the actual eye socket and the upper cheek. As we age, this area becomes progressively hallowed due to the sagging of the skin and fat along with muscle atrophy in the region. However, many also have a genetic component (inherent anatomy) to under eye hollowness, which is what we are seeing in your case. Volume restoration is the key to giving you the rested and youthful appearance you are looking for. Temporary options include fillers that last for varying lengths depending on the type and amount injected. It is vital to choose a filler that has an appropriate density so that it remains in place and does not dissipate within the area due to contraction of the muscle needed to close your eyes. Furthermore, certain fillers, if placed superficially, can lead to a Tyndall effect where a blue hue is seen on the skin. Permanent fillers also exist, but do carry a risk of reaction by the body seen even many years down the line. Other permanent options include fat grafting using autologous (self) or exogenous (outside) adipose tissue. However, fat grafting can, at times, lead to uneven contouring (e.g. lumpiness) if not performed correctly. Implants can also be placed along the tear trough, but can run the risk of infection, displacement, and extrusion if not appropriately placed. A permanent solution I believe would be best suited for you is called a suborbicuarlis oculi fat (SOOF) lift which involves a small surgery. Since you have a youthful upper cheek, the fat in this area can be re-positioned upwards to lay over the lower portion of the hallowing seen under the eyes allowing for a smoother transition from the cheek to lower eye lid. Ultimately, it is important to discuss all options with your surgeon to determine the best outcome for your desired look. I wish you all the best!!
