Facial contouring with fillers is an art and is possible. You have to see someone who is an expert at filler injections. I frequently use cannulas to fill large volumes and reshape peoples faces. There are many types of fillers that can be used for this purpose and all depends on a persons finances, long term goals, and needs based on an in person cosmetic consult. Seek a board certified cosmetic dermatologist with expertise using all types of fillers including HA fillers, Sculptra, Radiesse, Silikon ect. Although no a days there are many people injecting this products including nurses, PAs, noncore physicians, I would highly consider going to an expert in the field who is well versed in the up to date techniques. I wish you the best of luck, Dr. Emer.
