Thank you for your question. Usually, the appropriate way to inject filler to correct the tear trough area is deep to all the soft tissue structures, right on top of the bone (medial and lower portion of the orbital rim). That would place it deep to the orbicularis oculi muscle. That said, swelling at this stage is absolutely expected, the soft tissue layers in that area are all very thin, and it is near-impossible to tell by swelling alone where the filler was actually placed. You should always contact your injector ASAP with any concerns, but I suspect they will recommend to give it a full 7-14 days to allow for the swelling to resolve further, before they consider your result final. Hope this helps!
