It took several months to be completely back to normal

I had chin lipo in Nov 2017. It turned out great in the end but I had a known but rare side effect of my lower lip not being able to move down. So that I couldn't smile and had a slight lisp. Dr. Friedman had not ever seen it before with his patients. He followed me closely with after care until we saw what he predicted that it started resolving. I'm doing this review now because I've gotten so many messages over the years asking me if it resolved because of the question I posted here when I was dealing with it.. Yes it fully resolved. It took several months to be completely back to normal. One side got better a little faster than the other. Within Six to 8 weeks it was good enough that I had function but my smile was still weird then better and better each month until it was totally normal.
