Thanks for your question, but it is not really possible to answer this type of question without reviewing photos and knowing how and where the filler was placed. In general, with respect to the marionette region, there can easily be disappointment in terms of correction if there is a lot of skin laxity. If so, it is important to correct mid face volume loss as well and consider skin tightening in conjunction with the dermal filler placement to achieve the best, most natural and longest lasting correction. Also, 3 syringes sounds like "a lot" but remember it is really 3 milliliters. It would not be unusual to use 5-6 syringes of filler to achieve a full face rejuvenation in a 58 year old, add 1 more to "touch it up" about 2 months later, then "ride" the results for an extended period of time, particularly if it was Bellafill used. You have to achieve "full correction" in order to get a long lasting result. If you under-correct, the filler will seem like it went away too quickly but in fact it's just that the soft tissue swelling resolved and the filler volume left behind was not enough to do the job. Another trick to potentially extend the "life" of the result is to combine the filler injection with injection of platelet rich plasma (PRP)- the so-called Vampire FaceLift.Best,Lisa Vuich, MD
