[Question] I am curious about effective procedures for under-eye fat and how long the results last.

As I get older, the fat under my eyes gets puffier, making me look tired and older.
I am looking into common procedures like under-eye fat repositioning or laser treatments, and I am wondering which one would be the most effective.
Could you possibly tell me in detail the average treatment period for each procedure and how long the effects last after a single treatment?
