Dermal fillers are excellent for mid face volumizing and low face volume loss. What they are not indicated for are under eye hollow and tear troughs. This area of the face has thin, unforgiving skin. The dermal fillers by nature are meant to draw in water making them hydrophilic. The combination of thin unforgiving skin along with a "water binding" dermal filler is that you can be left with fluid pockets that do not go away unless injected with a hyaluronidase. Even after injection of this dermal filler dissolving agent, the prediction of where and how much dermal filler it will remove is completely unpredictable. The other down side of having dermal filler placed in such a delicate area is something called the "tyndall effect" which essentially is light reflecting off of the superficial dermal filler causing a bluish hue. This bluish hue will leave the under eyes looking darker and even more hollow. Even if one has seen a patient do well with dermal fillers immediately post procedure, these effects take days to be acquired. This is why 'before and after' photos may not present with these effect. Also there are some patients who don't experience these effect but because there is no way to predict if one will be left with permanent or lengthy unsightly side effects, a conservative experienced injector will NOT perform this procedure on their patients.Fat grafting also required a very skilled plastic surgeon. This procedures requires expertise, specialized instrumentation, and oatience on the part of the physician. Viewing before and after photos is only the first of many steps a person needs to take before trusting someone to make a possible permanent chance to their under eye area, but viewing patient photos, each from three different perspectives with similar lighting, distance from the camera and cropping is essential.
