Will dissolving my overfilled right eye cause premature sagging and wrinkling in that area?

Hyaluronidase will have best effects for over-treated areas when applied within a couple months post-HA filler injection. Hyaluronidase will not cause sagging of the skin. Patients who have been over-injected often fear that all of their filler will be removed after having Hyaluronidase or that they will appear diveted and depleted. This is not necessarily true if injecting with an experienced injector who can evenly spread hyaluronidase in targeted areas. I recommend that you seek in-person consultation with an experienced injector.Best, Dr. Anil Shah

The advantage of using a hyaluronic acid-based fillers is that the filler can be dissolved if the result is not what was anticipated or if there is some form of adverse reaction. The general claim that hyaluronidase only dissolves injected hyaluronic acid and does not dissolve surrounding native hyaluronic acid flies in the face of some very important facts. For one thing, before hyaluronidase was ever used for dissolving injectable fillers, it was used in normal tissue to help disperse other medications. What's more, recently, it was used successfully for softening tissues around the mouth (in order to permit greater mouth mobility) in patients with scleroderma (where no hyaluronic acid was injected). And I have personally used hyaluronidase successfully to help shrink tissues, such as excess fat under the chin. So, the short answer to your question is that it is possible that there may be some additional laxity in the region where the hyaluronic acid is dissolved. The good news is that a skilled, experienced physician injector will very likely be able to re-treat the region properly with filler to achieve the results you originally desired. Make sure that you consult with a board certified aesthetic physician and be certain to ask to see his/her personal before and after photos. Best of luck to you. 

Combining hyaluronidase to dissolve the filler with a skin tightening procedure would be optimal for the reason you describe.  My suggestion is Plasma Pen which is very effective in tightening lower eyelid skin.

It’s been my experience that dissolving HA filler under eyes should not  cause the area to sag and look thin more so after treatment as compared to before treatment. It goes back to how it  looked before.

Hello there,
      When something is over-filled, it causes excess swelling and stretching of the tissue. When the filler is removed, it will take time for that skin to tighten back up. There may be some instances where it does not completely tighten back up to its' original shape (similar to a pregnancy belly). That being said, if you are not happy with the appearance of the filler, I would definitely remove it so that you can address the area of concern in a more productive way. You may need non-invasive treatments to encourage tightening and rejuvenation in this area. You also may need to consider surgery to remove any excess skin and restore volume where it should be found. Hope this helps.

Dissolving filler under the eyes will not cause increased thinning or sagging of the skin. The skin should revert back to what it looked like before you had the fillers.
