How long would it take for swelling to go completely down after chin reduction surgery? (Photos)

I am considering getting chin reduction surgery but when I try to do research I can’t find much info. Considering I would have my bone shaved& some soft tissue removed.. there is swelling after the procedure but my question is how long will it take for the swelling to go completely down? I just don’t want to feel discouraged in the healing process. I read somewhere it can take 3 months but I read elsewhere it can take 6. Recovery is my main concern.
