It's called Voluma, and it's a gel that promises to fill out cheeks that tend to sag as we get older.
Treatments cost $1,000, and some patients may need several treatments.
Temporary side-effects include tenderness and swelling.
There are similar fillers on the market, but Voluma is the first specifically designed for the middle of your face.
It's also reversible, in case the patient isn't happy with the results.
