23 yrs old looking to correct sunken eyes (tear trough) with Hydraulic Acid injections or Juvederm. I have never had much fat or volume underneath my eyes and my dark circles are really noticeable. What bothers me is the gaunt look I have under my eyes and I would like to plump up that area to make it smooth. I'm worried about overfilling and having eyebags. Will .5ml split between both eyes be enough for a noticeable difference?
