Restylane injected tear trough is swollen and bruised 3 years later. Please help!

Restylane in the tear trough area may last for years, and the 'blue' colour is likely attributable to the 'Tyndall effect'. Indeed, I have had many patients referred to me with very similar presentations - swelling and/ or discolouration and/ or lumpiness due to hyaluronate fillers being injected in the under-eye area (e.g. too superficially ( too close to the surface), or too much, or the wrong choice of product). 
It is very likely that Restylane is still there; so, the focal use of hyaluronidase enzyme to dissolve the filler is quite likely to yield some success. My advice is that you try the dissolving option first, prior to more invasive approaches, and you shall also find some improvement in the colour - note that I only wrote 'some' improvement, and that is because skin that is less taught has a darker hue (meaning that when the filler is removed, your skin shall be less stretched and, hence, naturally look a bit darker).

Bruising, swelling, sometimes discoloration, lumps, and bumps are normal side effects assuming proper injection. They should be gone in a matter of days. In general, if it continues to feel uncomfortable up to this time, consult your doctor to get a complete assessment or have the filler dissolved if filler is still left.

I'm sorry to hear of the issues you have had with your Restylane treatment.  I encourage you to visit with an experienced injector near you for a consultation.  If it is determined that some product remains, you can consider having it dissolved.  

Hello and thank you for your question and photo's.  It looks like you have a tyndall effect where the filler is too superficial and it not only has a purple hue to it, it can last there for years.  I would find an experienced injector and have them inject hyluronidase which is an enzyme that is used in very minute amounts and dissolves the filler .  

Many thanks for your query.How does the lower lid feel ? If lumpy see your doctor as perhaps hyalase could help?Pigmentation under the eyes is likely to have been present before the filler - little can be done to improve the colour. You will need to hide this under makeup.BestMark
