Since Juvederm Voluma is very long-lasting filler you typically would not need to be treated again for a long time…up to two years or more. However re-injection may be needed a few weeks after your initial injection if you need more volume or more lift. Often it is better to be conservative and touch-up if needed. I personally see so many people who have been over-injected or overfilled and this is especially true I find for cheeks and lips. While certain people in the entertainment business for example may with intentionally desire a bit more exaggerated look, I have a very strong commitment to creating a very natural, soft, rested appearance. It is nearly always better in my opinion to remain natural and understated — especially if you have never been treated before. Juvéderm Voluma does not require as much volume as other hyaluronic acid fillers to create the effect you want and so care must be taken for injectors who are not as experienced with Voluma to not overdo your treatment. Allergan, the creator of Juvederm Voluma XC has made exceptional efforts to provide proper training for Voluma and it really is very important that you have an experienced injector.
