Is Perlane a good choice filler for under eye (hollow) treatment? Is it better than Juvederm?

You would be better off using Restylane or Belotero.  Juvederm can swell quite a bit and you may look overcorrected.    

Juvederm can have what is called the tyndall effect that can cast a bluish tint, so it's not usually the best choice for that area (but great in many other locations).Restylane is a good choice for most anyone because it does not have that potential for the blue show through. Restylane and Perlane are the same basic product except Perlane is a little denser. This makes it a viable option for some people who have thicker skin, but if the skin under your eyes is fairly thin, Restylane would likely be a better choice.

Hi Snow White,The best filler to use for the under eye hollows is Restylane.  All other fillers may cause too much swelling and edema.  Perlane should not be used under the eyes.  Most importantly, choose your injecting filler most carefully.  Good luck and be well.Dr. P
