Is It Safe to Add Juvederm to Lips with Restylane?

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.
