Hi PP,
Juvederm has a longer track record of effectiveness and safety. I am unable to comment on Teosyal as it has not been approved for use in the US yet, and I have not had any experience with it.
Juvederm Ultra Plus is excellent filler for facial volume. If you are having the delicate lower eye lid included in your treatment, you might ask for Restylane in that area (less likely to swell).
Good luck and be well.
Dr. P
