I have numbness on my lip to the left of the incision line. Initially it was completely numb, now only partially so. It took a little while to get used to, but it's really no big deal. It can be a bit embarrassing when eating ( you tend to drool a bit) but I find I wipe my lips with a napkin frequently, and it's a non-issue

No drooping (that's something that tends to be the result of a surgeon in a hurry, not a legitimate side effect).

Good luck with your decision

Minnie is absolutely right re: functionality vs. cosmetic. I sense it is a functional improvement here
