It’s possible that residual filler could be contributing to heaviness or increase the appearance of the jowls, especially with a firmer HA filler like Voluma. Over time, filler can shift, retain water, or simply become less supportive. Strategically dissolving part of the filler can improve contour. However, it’s important to remember that some of what you’re seeing may also be related to the natural progression of skin laxity and tissue descent that continued naturally over those 3 years. The key is determining whether the issue is residual filler creating bulk/heaviness, true jowl formation from laxity, or a combination of both. An experienced injector can often assess this by palpating the area and sometimes using ultrasound to evaluate how much filler is still present. If significant filler remains, gradual dissolving may help restore a softer, more balanced contour. Depending on the degree of laxity, additional options after potential dissolving may include biostimulatory treatments (such as Sculptra or hyperdilute Radiesse), RF microneedling/skin tightening, PDO threads, or surgical lifting procedures. I hope this provides you some clarification!
