What can be done for discoloration after fillers to mask festoons? (Photos)

Infraorbital swelling and Tyndall discoloration due to inappropriate filler placement, overfilling or filler displacement is typically treated with the filler dissolving enzyme, hyaluronidase. If the swelling is due to lymphatic obstruction, i.e. lymphedema, the problem usually requires more aggressive treatment and multiple treatment sessions that include not only hyaluronidase, but additional anti-inflammatory agents, in varying concentrations and amounts. Hope this helps. Best of luck.

Although it would take an in person exam to know for sure, you do not appear to have any Tyndall effect but residual shadows from depressions that were not addressed originally. If this is what you have, it can be corrected by an expert injector. However, these are hard to find as most injectors do not understand the anatomy, precautions, or modern techniques for the region. Do your research and do not accept superficial injections, especially near the eye.
