After hyaluronidase, how does the dissolved product leave the body?

I'm having product (Restalyne and Voluma) around my eyes removed due to overfilling. Someone mentioned to me that as the old filler product dissolves, some of if may melt/slide (?) down from the original location, potentially making the area below more my eyes (midface, etc.) more pouchy than before the filler was dissolved. I assume this may "look" like the case after the eye filler is removed, but it's a question. Can any filler liquify enough to slide elsewhere on the face?

Hello There, 

Hyaluronidase is an enzyme that liquefies the filler and turns it into water immediately. This is then absorbed by the body. It may initially look a bit swollen, or as you state "pouchy", due to the added fluid, but this will resolve within a few hours. Not all filler can be reversed with this product, as it is only effect for hyaluronic acid based fillers. Bellafill, Sculptra, and Radiesse are not among this family. There is a small risk for filler to migrate if it is not placed in the correct plane, but it would not liquefy and travel. 

Hope this helps,
