Hello and thank you for the question and the photo. based on the photo and your goals, it would be recommended to have liposuction and fat transfer. There are no appropriate implants for this. I would suggest having liposuction above and below the "dip" followed by fat transfer into the dip....
The cvost for fat transfer to the peri-orbital zones of the face is based on the individual surgeon's clinic, experience, use of anesthesia and facility and other factors.
I suggest you see an expert you can sculpt the face with a combination of fillers, neck kybella/liposuction, or facial ultherapy/thermage. Best, Dr. Emer.
