Bulging under right eye after Juvederm 1.5 ml. Would I benefit from more filler? (photo)

I recently lost weight rapidly due to a medication side effect but have since gained most of it back. lost quite a bit of volume in my face and decided to get dermal fillers in my cheeks and undereye hollows. I've attended 3 different appointments but still have not achieved my desired look under my right eye. I know one side can have more collagen but I already have 1.5 ml under there. What is that bulging? a ligament? Should I get more filler or is this as good as my eye will get?
