Will it be uncomfortable when speaking or smiling after philtrum reduction surgery?

My philtrum is on the longer side, so I'm looking into philtrum reduction surgery. However, after reading reviews, I'm really worried because some people mention a pulling sensation when talking or smiling. I tend to talk a lot and smile frequently, so my biggest concern is that my facial expressions might look awkward. They say it returns to normal over time, but I don't really have a sense of how much it actually recovers.
