Radio frequency probe to dissolve HA filler?

The causes of persistent hardening at injection site include using the wrong HA filler under the eye, incorrect placement, infection, granuloma or nodule. In your instance since Hyalurodinase has failed, an expert physician injector's opinion would be strongly recommended before using Radiofrequency or Ultherapy to dissolve the filler.

Hi and thanks for your question. First make sure that they used a HA filler otherwise hyaloronidase is it going to be effective.  No scientific evidence that RF can dissolve it but you can try of hyaloronidase not effective 

Thank you for your question - I would recommend having an ultra sound guided hyaluronidase injections directly INTO the filler to dissolve it - there isn't any confirmed benefit to radio frequency probe to break it up. IF it wasn't hyaluronic acid filler that was used than hyaluronidase will not work. Any HA filler (brand Restylane or Juvederm) dissolves immediately with hyaluronidase so confirm what exactly was used. best of luck

Consider ultrasound-guided hyaluronidase injection to confirm proper placement. Will not work if a non-hyaluronic filler was used. 

Thank you for your question. There is no scientific evidence that intradermal RF can dissolve hyaluronic acid dermal filler. I recommend continuing with hyaluronidase injections. Good luck ,
