It seems like the hollowness under my eyes has gotten worse. What should I do?

I am very worried because the hollowness under my eyes seems to be getting worse lately. At first, I thought it was just due to fatigue, but the changes have become much more noticeable lately. Has anyone here ever addressed this issue? I am curious to know which procedures or treatments were effective, as well as what the pain and recovery process were like. I would also like to hear the experiences of people who are not much older than me.
