Is There a Cumulative Effect with Juvederm?

the filler itself does not accumulate, but the actual procedure induces more of your own collagen as you have continued treatments.

Certainly you can overaly Juvederm on top of previously injected material. It is also thougth that overtime, the collagen under the skin is stimulated as well.

Juvederm acts by acting as a space occupying material which attracts water. Although it also acts by causing the body to produce some collagen each time it is injected, that is NOT its major mechanism of action. After multiple Juvederm injections, the recurrent creation of collagen may result in some residual permanent filling.
