Hi. I just recently had my first juvederm treatment in my tear trough area and am very pleased with the results. My dark circles and puffiness are not completely gone but majorly improved. My doctor used approximately half of my syringe for both eyes and asked that I come back in about a month to see if I would like to use the rest. He said that less is more and that he wanted to use a conservative amount to avoid overfilling. I am planning on returning and requesting a tiny bit more to completely eliminate my dark circles. The procedure only lasted about 20 minutes or so and I was able to apply makeup shortly after. It did hurt some but worth the pain considering the gain.
