Spent a lot of time in front of a mirror figuring out exactly which muscles to pull and which to freeze

I am not an expert by any means, but as far as I know, no. There are lots of little muscles in and around your face that most people never use, and if you’ve never used them, then you won’t know how. I’m pretty sure it’s possible to learn how to use these muscles, but I wouldn’t be able to give any advice on that part. It’s similar to how some people can wiggle their ears

When I was a kid I wanted to be able to raise one eyebrow, but I couldn’t figure out how. What I did was use my hand to raise it over and over again to kind of train the muscle. Eventually I could do it without the help of my hand! Also a fun fact: I only ever did it with my left eye brow for some reason, and now that’s the only one I can move on it’s own.
