Hyaluronic acid filler is so versatile - it is used to fill wrinkles, plump folds, augment lips, make chins and cheeks larger, and so much more.  And when you're 40 or 50, it really can stall the need for a facelift.  But eventually, years of filler may give you the "overfilled" look and have diminishing benefits.  And that may mean it's time for a facelift.  On this program, cohost Susan Warner and Dr. Perry discuss when it's time for a facelift and when filler no longer is helpful.
