I'm trying to decide between Juvelook Volume and fillers. Which one looks more natural?

As I get older, my cheeks and under-eyes look sunken, making me look so tired and aged, which is really stressing me out. I'm worried that fillers might look artificial or sag over time, but I've heard that Juvelook Volume works by replenishing my own collagen, so it looks natural. I'm wondering how many sessions I would need to see noticeable results. If anyone has tried both procedures, could you honestly share the pros and cons?
