Thank you for your inquiry. It appears that the fillers have helped. In my opinion, your options at this time include manipulation of your existing filler, removal and replacement if necessary, or injection of extremely fine lines of Belotero Balance placed extremely superficially. The latter option is technically demanding but can produce beautiful results. Best of luck.
The key is who is doing the injecting. Not all injectors will be comfortable placing volume in this area. I recommend that you talk to whoever did your current lower eyelid service and have them place more volume.
