I'm curious about good treatments for under-eye fat and dark circles.

Lately, I've been worried because it seems like the fat under my eyes is increasing and my dark circles are getting worse. I look tired every time I look in the mirror, so I'm considering getting a dermatological procedure. I'm curious what kind of treatment is usually most effective for my condition. Also, if I undergo the procedure, how long should I expect the treatment and recovery period to be? Since I work, I'm concerned about whether it will interfere with my daily life. Or should I schedule a longer period, like a summer vacation? How long does it take to return to normal routines? They tend to stand out more whenever I'm not feeling well, so I want to take this opportunity to properly resolve the issue. I would appreciate your advice on the approximate duration of the treatment or any recommendations you have.
