Zygoma (cheekbone) reduction surgery recovery experiences?

I have prominent cheekbones that make my face look wide from the front. I am considering zygoma reduction surgery in Korea. I understand this is a major surgery that involves cutting and repositioning the cheekbone. Can anyone share their recovery experience? How long were you in Korea post-surgery? When did you feel comfortable being seen in public? I am particularly worried about the potential for sagging skin after the bone is reduced. Did anyone experience this? Also, how long until you could sleep normally without worrying about the surgical site?
