What is the most effective procedure to resolve under-eye hollowness and dark circles?

Lately, whenever I look in the mirror, the area under my eyes looks dark and sunken, so I often hear people around me say that I look very tired.
Even on weekends when I get a good night's sleep and feel at my best, I have dark circles under my eyes that reach down to my chin, making me look much older and causing me a lot of stress.
I have been diligently applying expensive, highly nourishing eye creams, and I am considering salmon injections because I heard they are effective, but I have heard that the treatment method varies depending on the cause of the dark circles.
I was told that if it is simply pigmentation, I need to get laser toning, but if the shadows are caused by protruding fat under the eyes, I need surgery.
When I touch the area under my eyes, the bone feels prominent and it feels slightly sunken. In this case, would filling it with under-eye filler be the most effective solution?
If any Maypure members have received treatment for severe dark circles and experienced the magical effect of their eye area brightening up, please share your tips.
Since the skin around the eyes is sensitive, I am curious and worried about whether there are any side effects, such as unevenness or a bluish tint, if fillers are injected incorrectly, and how long the effects last.
If you have any vivid personal experiences regarding dark circle treatments or advice on what to know before visiting a clinic, please feel free to leave plenty of comments.
