I know people have been asking about facial changes, and I was very curious about this as well. I might just be imagining all these, and the changes are definitely very very tiny, but some of these have been confirmed by my parents. They don't see me very often, and just saw me now after I finished expanding.
Some of the changes: face seems a tiny bit more rounded, cheeks seem a bit fuller (someone even wondered whether I'm going to develop dimples), i think that because of the cheeks my eyes don't look as droopy anymore and seem a tiny bit bigger. And of course the nice, wide smile. Again, I might just be imagining this, and I've definitely started taking better care of myself: makeup, new haircut, painted nails, new clothes, etc just to compensate the huge gap I have

I had a great experience with the surgery, and I would recommend it to anyone who had to choose whether or not to get it.
