White looking bulge under right eye? Is it muscle, fat or scar tissue? Please help my PS doesn't know (Photo)

First surgery in Jan 2022 - midface lift, upper and lower blepharoplasty with canthoplexy and muscle suspension. Revision surgery in August 2023 - lower blepharoplasty to correct herniated fat that wasn't there prior to surgeries. Removal of herniated fat, septal reset, cantoplexy and muscle suspension. Can anyone give me advice as to what is causing this.
