Thank you for your question. I'm sorry to hear that you are unhappy with the results of your under eye filler treatment. Do you remember which product was injected under your eyes? Assuming you were treated with a hyaluronic acid product (Restylane, Belotero, or Juvederm products), hyaluronidase should be able to effectively dissolve your filler. It may take more than 1 session to fully reverse the effects of your filler, but it can be done. That said, the under eyes are also particularly prone to swelling after filler injections. While this swelling typically resolves within 2 weeks for most patients, I have seen a handful of patients who have experienced swelling for longer periods of time (sometimes up to 4 weeks or so). I would recommend following-up with your injector to discuss your concerns. Best of luck!
