How Long for Radiesse Nightmare to Dissolve Under Eyes?

In the short term, I advise oral as well as topical Arnica to reduce any bruising and swelling.  Unfortunately, this could take a while to resolve, minimally a year.  But it gradually improves.  I have seen it take a few years.  What you can do, once all the swelling from the procedure has resolved, is to try and correct the way it looks by having Juvederm or Restylane injected--this is to compensate for any hollows caused by the Radiesse.  I suggest you go back to the doctor who performed this procedure.  Work with him.  I advise against cutting it out.  The scars will be permanent.

I personally prefer to use Restylane to treat hollows under the eyes.  Witout much movement in this area, products tend to last longer (as compared to areas like the nasolabial folds, where there is a lot of movement). Restylane may last more than a year when placed under the eye. 

Radiesse tends to last longer than Restylane in the skin.  In the nasolabial folds, Radiesse can last longer than a year.  So if place under the eyes, Radiesse will likely last even longer.

Unlike the hyaluronic acid fillers (like Restylane / Perlane / Juvederm), which can be removed wtih an enzyme called hyaluronidase, there is no eraser for Radiesse.  The best treatment for overfilling with Radiesse is a tincture of time.  Over months to years, your body will remove the product itself.
