Lower eyelid fat repositioning inquiry

I brought an image that looks similar to my eyes.

I don't have bulging under my eyes, but the area beneath my eyes is sunken and I have severe dark circles.

I had some dark circles when I was young, but as I got older, they worsened and sank in, making me look always tired and older.

However, many people warn that the side effects are severe and frightening. Is lower eyelid fat repositioning surgery very risky? And after the procedure, can the hollowing under the eyes be improved?
