What chemicals or ingredients are in Juvederm?

The essential ingredient of Juvederm is Hyaluronic acid which is the same ingredinet among many other fillers such as Restylane, Hylaform, Perlane, Prevelle Silk. It is a naturally occuring product that is in the deeper layers of the skin and among the class called glycosaminoglycans. This is manufactured by taking the human gene and transferring it to bacteria (recombinant DNA) in order to use them to mass produce the hylauronic acid. The process to refine the hyaluronic is proprietary..

Juvederm is a  hyalruonic acid that is normally found in the body and is used as a great filler product for facial rejuvenation procedures.

The Juvéderm product line is well-known for its smooth consistency that results in a natural feeling and look.Juvéderm is safe and effective and is created from non-animal stabilized hyaluronic acid made in laboratories from bacterial cultures. Hyaluronic acid is a naturally occurring substance in human skin. Juvéderm fillers also contain lidocaine, an effective, localized pain reliever for extra comfort during your injection treatment.

I don't have a syringe nearby to read off the exact formula but I am sure you can get it from their web site. Basically, the workhorse in Juvederm is hyaluronic acid (HA), just as it is in Restylane. There are claims the there are chemical differences between these two products but both are HA fillers.
