Will Ultrasound Waves Help Dissolve Restylane?

Once there is swelling and bluish discoloration from Restylane or Juvederm, the only way to lessen it is by physical extraction (by the physician doing this in a sterile fashion, not you) or dissolving it with hyaluronidase. I am not aware of ultrasound improving this as it should not degrade it.

The blue tint your describe is called the Tyndall effect, which occurs after placment of Restylane in a less than ideal depth or in skin that may be too thin.  The best way to remove the Restylane is with hyaluronidase if you want it out right away.  Ultrasound is not the choice treatment.  The presence of factors affecting periorbital blood flow can also compound the Tyndall effect, and patients undergoing filler injections in the tear trough area need to be thoroughly evaluated and treated for these issues before proceeding. 

The issues you have in your lower eyelid are minor and are easily adjusted with hyaluronidase, the enzyme that breaks down the filler.  You need a very experienced injector who knows what they are doing.  Don't be discouraged by this bit of swelling which is easily adjusted.
