A filler will only add volume to your face if you have lost facial fullness. This is in contrast to the facelift which will actually lift your sagging soft tissues and eliminate skin redundancy. So whether you need filling or lifting is dependent on your specific needs. A consultation with a facial surgeon will help you decide what is in your best interest. Finally, you may choose to have fat grafting rather than a filler since your own fat will be permanent and not temporary.
