Restylane in Tear Trough Caused Dark Shadow? (photo)

I would give yourself another couple of weeks as this can still be residual from bruising. If not better, see your doctor

If there is a fair amount of bruising after filler injection, the residual blood can take a few weeks to absorb completely. I highly recommend sun protection during this time because UV can cause some of the remaining blood to take on a muddy brown appearance. This is especially true during as spring/summer approaches. While the darkening is almost always temporary, it can take months to resolve. If on the other hand, the discoloration is more bluish in color, that may be restylane that was injected too superficially in the skin. If that is the case, the only way to rectify the color issue is to dissolve the restylane with hyaluronidase.
