Have you seen significant improvement in your dark circles with under-eye fillers?

I am very stressed about my dark circles and hollowness under my eyes, so I am considering getting under-eye fillers.

I've been told that even covering it with concealer has its limits and that I always look tired, so I'm thinking about getting a procedure. However, when I look at reviews, there are many people who were satisfied, but there are also many who regretted it.

I am especially worried because I heard that the skin under the eyes is thin, so the filler might show through or become bumpy.

I can't easily make a decision because there are reviews saying that the filler shifted over time or bulged out like a caterpillar.

Has anyone here ever had under-eye fillers?
