Filler for under eye
As you can see from below, there are a lot of filler options for under the eye. Deciding on the right one for you will require an in person exam. I would advise you to schedule a consultation with a board certified plastic surgeon or cosmetic dermatologist in your area (link below) to discuss. best, Dr. Nazarian

It appears that you still have a little volume loss under the eyes which would benefit from Belotero or Restylane to that area. Best, Dr. Green
