Is It Safe to Add Juvederm to Lips with Restylane?

Absolutely.  Juvederm and Restylane belong to the same class of HA fillers and can be combined.  I would recommend an Arnica based ointment like Bruise-Stick before injection of facial fillers. 

There should be no significant issues with adding the Juvederm to your lips for volume enhancement and further reshaping. Both products are based on hyaluronic acid and can be blended without much consequence.

It is totally safe to inject Juvederm into an area where you have already had Restylane injected. The products are very similar and in my extensive experience there has been no reactions between the two fillers. You should always seek a board certified physician for these types of injections, because the skill and experience of the injector is critical in preventing lumps.

There shouldn’t be any chemical reaction between the two, but there can be (very rarely) delayed reactions to a filler. If you develop a reaction in the future, you might not know whether the Restylane or Juvederm was responsible.
However, it is not unusual for physicians to layer different fillers on top of each other placing the thicker filler deeper and the thinner filler on top. If your lumps occurred immediately after the treatment, please realize that they may easily be extracted by the doctor through a very tiny sterile needle puncture and expression.

Hi Daisy Bell,
Relax and enjoy the Juvederm Ultra Plus.  It is perfectly safe to add Juvederm to lips that already have Restylane.  Good luck and be well.
