Is it okay to get a Bellafill injection before a previous Juvederm injection in the same area has worn off completely?

It should be perfectly fine. There is no contraindication for Bellafill being injected on top of Juvederm. 

It would be okay to have a Bellafill injection after Juvederm was injected into the same area.  You will need to have a skin test for the Bellafill first and this normally needs to watched for 4 weeks to make sure there is no allergy.  The get the best results with Bellafill, several treatment sessions are normally needed to provide gradual, lasting improvement.  

Hi and thank you for your question. Yes, you can have Bellafill after Juvederm injections have resolved. It sometimes takes a series of treatments to get desired results with Bellafill. Bellafill results are gradual over a few months. Hope this helps. 

Some Doctors will recommend having the Juvederm dissolved before placing a permanent filler. I recommend following up with your injector about their recommendations. It will take several months for results with Bellafill. Best, Dr. Emer

Thank you for your question.  Yes, it is fine to inject Bellafill in an area that has other kinds of filler.  When Bellafill is injected on top of other filler, it should be done to full correction, not overfilled.  The Juvederm that is still present in the area will dissipate slowly and evenly over time, and there will be a reduction in volume when the Juvederm is gone.   You can then go back and refill to correction with Bellafill.   I sometimes inject Bellafill along with a hyaluronic acid filler such as Juvederm in the same treatment, in order to bring down the cost of full correction.

There is no interaction or detrimental effects by injecting Bellafill into an area which has other fillers such as Juvederm. This is often done in a layer technique to provide best outcomes in fact. I will use Bellafill as a deeper filler and then place an HA filler such as Restylane when correcting eye hollows.

Thank you for your question. There is no problem with switching over to Bellafill at this time. As your Juvederm further dissipates over time, you will likely require additional Bellafill which is just fine because you do not want to over-correct with Bellafill given the relatively permanent nature of its effects on collagen production.I hope this was helpful - Dr. Moore.

Hello and thanks for posting.
There is no problem transitioning from Juvederm to Bellafill and this is a common strategy in our practice. The reason that this works so well is that Bellafill is not a one-time treatment, even though the PMMA component of the product is permanent.  Several sessions of Bellafill injections are typically required over a period of several months to achieve full correction and a durable result.

The traces of Juvederm that are left are not going to negatively affect the outcome.

Good luck!

Juvederm and Bellafill work in two different ways so adding Bellafill as a filler for your nasolabial folds now, 14 months after your Juvederm injection is not a problem.  You should get a great result if you liked what you got from your original injection.  Just remember that you may need to add a little more in the future when the remaining Juvederm dissipates completely.  
I hope that helps.
Best regards.
