I'm looking into eye fillers because of the hollowness under my eyes. Will it be effective?

I hear so often that I look tired, so I looked in the mirror and noticed that the subcutaneous fat around my eyes had drained away, leaving them deeply sunken. It even cast shadows like dark circles, making my complexion look dull, so I finally decided to get filler injections around my eyes.

Since the skin around the eyes is the thinnest and most sensitive area, I am worried that getting fillers there might result in unevenness or show through. I am not sure if filling in the sunken areas will definitely brighten my complexion, or if it will feel unnatural. It is not a cheap procedure, so I have no choice but to be cautious.

If anyone has received filler injections around the eyes at a dermatology or plastic surgery clinic, could you please share your honest review regarding your overall satisfaction and whether the shape takes naturally?
