Juvedurm in Tear Troughs Caused Permanent Bruise/dark Circle Under One Eye? (photo)

If the area appears raised or bulges out at all it is probably Juvederm which is more likely than other fillers to swell and look blue under the thin skin below the eyes.  If this is the case I recommend you have Hyaluronidase injected into the area to dissolve any residual Juvederm that may be in the area.  Did you go to an experienced cosmetic specialist?  Experienced cosmetic physicians who inject below the eye do not usually use Juvederm in this area and also usually know how to inject deep enough to avoid this problem.  Of course, occasionally it can happen even with good technique and using other fillers.  If the area is flat and a dark blue color it may be hemosiderin (iron pigment from red blood cells that have leaked into the skin after bruising), in which case VBeam laser would help.

Tear troughs, hollows, and dark circles are common problems of the lower lids. It has become standard practice to treat this region with lighter weight fillers, like Juvederm or Restylane, to lift, straighten, and contour this region.

Occasionally, if fillers are inadvertently placed too superficially, a bluish discoloration related to light scattering (a phenomenon known as the Tyndall effect) can occur, which can actually make the dark circles more prominent. Sometimes, hemosiderin, a pigment that remains following bruising can remain leaving a troubling darkness.

Juvederm, which draws water to it after injection, would not be my choice for this region. Restylane, diluted properly, can give sufficient lift, without this concern for drawing water to it. Belotero Balance, however, a relatively new hyaluronic acid product, has been manufactured to avoid the Tyndall effect and is my preferred agent for treating undereye problems.  I have found that the addition of a tiny amount of Radiesse, a whitish-colored filler, to the Belotero Balance to be an excellent way of treating tear troughs and hollows and lightening existing dark circles. However, only an experienced, board certified aesthetic dermatology or plastic surgeon injector should attempt to treat this area in this fashion. Of course, if any Juvederm is still believed to be present, this should first be dissolved with hyaluronidase before initiating re-treatment as described above.  

Consider seeing an oculoplastic specialist for evaluation. The problem may be both hemosiderin deposit, shadow effect from continued hollowness, or other.
