Which would be better for my sunken under-eyes, Juvelook Volume or fillers? ㅠㅠ

Now that I've turned 10, I've lost weight in my face, and the area under my eyes and the front of my cheeks have sunken in deeply. Everyone around me keeps asking if I'm tired, and it's really stressing me out. I want to fill them up nicely, but I'm a bit scared of fillers because I'm worried they might sag or feel foreign later on. I heard that Juvelook Volume is better for a natural look, but could those of you who have tried it please share some genuine reviews on whether it fills in thin areas like the eye area beautifully without forming nodules?
