Best Filler for Hollow Under Eyes?

If you have hollowing under your eyes or what we refer to as early tear troughs I think the optimal treatment is not surgical at this time. Hyaluronic acid filler injections are good for this area of treatment. A filler such as Restylane placed very carefully along the supra orbital rim from lateral to medial in a very meticulous fashion gives excellent correction in this area and will last at least one year if not longer.  

Fillers under the eye vary, but I have recently been using Juvederm for most of these procedures in my practice. I have used Restylane as well in the past but find that it does not last as long. That said, both of these fillers' longevity I find to be markedly less than in other areas of the face. On average, I would say they last about 3 months in the under eye area or less.

It sounds like you are referring to the area known as the "tear trough".  My personal preference for filler in this area is Restylane.  However, other fillers are also used to fill tear troughs with good results.
