When does Voluma start to fade away?

Thank you for your question.  Voluma is one of the newest fillers and has reports of positive results for 2 years or more after the injections.  Like other fillers, Voluma will start to be slowly absorbed by the body as soon as it is injected, but it is a much slower absorption than others.  It is impossible to know how much longer the remaining Voluma will continue to have effects in your particular case, but the only other way to speed the absorption would be through the injection of hyaluronidase into the areas of residual filler.  Hope that this helps. 

Voluma typically lasts longer in comparison to other hyaluronic acid dermal fillers. It can last up to 2 years. That being said, it does break down over the 2 years. Therefore, the clinical results you had initially could be different at 6 months, 9 months and so on.

Voluma typically lasts between 2-3 years although it slowly goes down continuously. You could consider Hyaluronidase injections to disolve the Voluma immediately.  

You were treated about 15 months ago - which unless you were on the FDA clinical trials is near the 'early days' of the approved injection of Juvederm Voluma in the USA.  Based on the data from those studies a common answer is 'up to two years'.  Based on European experience (where this has been in use for many years) the answer might be different ranging from a shorter time tolonger - perhaps 3 years (the techniques and volumes used in Europe are sometimes different than the typical injection protocols in the USA).  I have seen quite a number of my patients returning in my practice who are 15 to nearly 18 months out who i injected using conservative volumes of 1-2 syringes who still are maintaining nearly 'full correction' and only a few who have begun to fade.  So there is a difference between the Voluma material being metabolized by your body and decreasing in quantity and the 'visible correction' that you see in the mirror.  You should probably ask your injector for advice on your specific case and technique and volume he or she injected.  Typically however the timeline varies considerably based on the volume injected, the anatomic site, the depth/location the Voluma was placed, the overall technique used, whether you have had weight loss, and other factors.  Injections of hylaronidase (an enzyme our bodies use to remove hylaronic acid) may be used to remove it sooner, but you should see someone experienced if doing this as the dose and brand of the hylaronidase that seems to be optimal for accomplishing this for Voluma is thought by some experts to differ from that used for other hyaluronic acid fillers.

A lot of this depends upon how much was injected and where on the face it was used. More syringes will require a longer time to go away "on its own". According to the FDA it should last "up to 2 years" with full correction. But this means it's going down over time, and it just won't disappear all of sudden at day 730 or something. If you want it gone, consider getting hyaluronidase injections to remove it right now. Then you don't have to wait at all. "This
