Consideration of methods and effects for improving sunken under-eyes

I am concerned about hollowness under my eyes and am looking for ways to improve it. I am curious about the changes you experienced through a specific procedure. I would also like to hear about the pain and physical changes during the recovery process, as well as how the reactions of those around me changed. Additionally, I would appreciate it if you could share how this procedure affected your sense of psychological stability and self-confidence.
