Under eye dermal filler swelling. Any idea what might cause this?

Hello,Thank you for the question about under eye swelling after tear trough filler.There are a number of potential causes here, and a few things need clarification. Is there any pain associated with the swelling? Does the swelling occur in the setting of a respiratory illness?It may be the body reacting to the filler. It may also simply be that there is too much filler in this area (fillers in the under eye can last many years). The fact that it is intermittent may be related to your hydration amongst other things.An option would be to simply reverse the filler (if it was a dissolvable HA type of filler). However it is important to first consult with your cosmetic doctor to formally assess the area before making a definitive diagnosis and deciding on the best treatment. I recommend that you arrange a consultation with an experienced cosmetic doctor to assess the issue properly.Kind regards,Dr. Aaron Stanes MBBS, Cosmetic Physician, Melbourne, Sydney & Brisbane , Australia.
