Will Juvelook be effective for sunken under-eyes?

My under-eyes look hollow and I have severe dark circles, so I was thinking about getting under-eye fillers, but I've noticed that Juvelook is quite popular these days. The reviews aren't bad either, so I'm wavering between fillers and Juvelook. What do you think about getting Juvelook for my under-eyes? I'm curious if it would be as effective as fillers.

I heard that with fillers, the under-eye area fills in immediately after the procedure, so you can see the effects right away, whereas with Juvelook, the sunken areas gradually fill in over time. I am a little worried about what to do if the volume doesn't increase as much as I want, but since my skin is quite thin, I am also wondering if Juvelook might be the better choice. I am really conflicted.

For those of you who got Juvelook injections under your eyes, how was it? I'm curious if you are satisfied with the results.
