This is a very good question. For one, sculpture is not permanent. Fat is permanent. In addition, sculpture often requires multiple sessions. A good rule of thumb is that one requires 1 vial of sculpture for each decade of life. So if someone is 40, they would require four vials each session. With 3 sessions this is of course 12 vials. And within 2 to 3 years just about all of it will be gone. Fat however is permanent. And fat can be injected over the entire face including around the eyes, eyebrow, temples, lips, buccal space, etc. It is much more versatile. In one can also use higher volumes to create more natural looking results rather than injecting into discrete locations that will ultimately make the face less proportionate, potentially. Sculpture does have a role. But it is inferior to fat when it comes to volumizing the face.
