How do you compare clinics that are good at facial contouring surgery?

I'm looking for a good place for facial contouring surgery, but I'm confused because the reviews all make the lines look beautiful.

I like having a smaller face, but I don't want it to be shaved down too excessively. ㅠㅠ

When choosing a good clinic, would it be best to go to one where the doctor examines facial proportions in detail during the consultation?

I'm also curious if swelling management and aftercare significantly affect the results.

Besides before and after photos, what else should I check when choosing a clinic for facial contouring surgery?
