Hello, the amount of filler depends on the location. Some of those stars on television have 2-3 syringes of filler in their lips alone while a more natural look is usually around 1-2 syringes. The studies on Juvederm Voluma (an excellent structural filler designed for the mid-face and cheeks averaged 7+ syringes in the cheek areas (of course they did not have to pay because it was a study). Around the age of 50, depending on the laxity of skin, smoking, sun damage, volume loss to due bone and underlying fat structure loss simply from aging, many women need 4-5 or more syringes to return the face to a more youthful look. It really depends on the person and their skin but a skilled injector should be able to direct you towards a natural look. Also, most hyaluronic acid fillers were designed to be layered on top of one another, so you don't walk out with a "done" or over-filled look. You can always go back and have additional filler placed. Good luck.
