Juvederm is typically priced per syringe. The unused portion of a syringe can be stored for a short amount of time (up to two weeks) but many doctors choose not to do this because of the risk of mixed-up syringes and the small but real additional risk of infection. What this means in practice is that you usually pay for a full syringe (or two) depending on how much of the filler your doctor uses.
There are two main types of Juvederm: Juvederm Ultra and Juvederm Ultra Plus. Juvederm Ultra Plus is thicker and used for filling deeper wrinkles and for extra plumping power. For each of these versions, you can also get the filler formulated with lidocaine, a painkiller. The versions with lidocaine are denoted "'XC," meaning you can opt for Juvederm Ultra XC and Juvederm Ultra Plus XC.
One .80 cc syringe of Juvederm Ultra typically costs between $400 and $800. Juvederm Ultra Plus costs between $450 and $900 a syringe. Add $25 to $50 to cover the additional cost of lidocaine with XC.
How to get Juvederm: Many doctors offer a price break for all syringes after the first. So for example, if you pay $500 for one syringe of Juvederm Ultra, the second might be just $400. Make sure to ask. Some doctors also give a price break if the injection is performed by an assistant under supervision.
