It is good to ask your doctor why he or she recommends a particular filler for you, if it is FDA approved for the area in question (although most doctors do use fillers for off-label areas), and how many times he or she has injected it (30 to 50 times is a good benchmark indicator that the doctor has sufficient expertise with that filler). Because every filler has a slightly different consistency, a doctor should understand how to deep to inject it, be comfortable with the type of needle to use and other factors associated with that filler.

According to the American Academy of Cosmetic Surgery, fillers like Restylane and Perlane have seen a 110% increase in procedures performed in the past three years. Botox, which doesn't fill wrinkles, but reduces the muscular contractions that cause them, has seen a 115% increase. Face-lifts, on the other hand, have only seen a 20% increase in the same time period.

The average price for fillers is $800 per session, according to the AACS. Compare that to a face-lift, which can run into the tens of thousands. "In this economy, some people don't want to pay [for] a facelift," says Dr. Fisher, who charges approximately $50,000 for a visage overhaul. "But they still want to look good for job interviews."
