I have to talk about something really dumb. But it comes to mind every time I hear someone complain about their resting b-tch face. So here goes…
Hot Take: RBF is a Choice 
People who complain about RBF, like it’s unique to them, just don’t understand how muscles work. And anyone who wants a more approachable face can have one.
We all have muscles in our faces, right? Well, when those muscles completely relax, the corners of the mouth turn down or flatten, the brow lowers to a comfortable position, and the muscularity around the eyes and cheeks go slack. Nobody in a fully relaxed state is “smizing” (smiling with the eyes) because there’s no tension in the face.
That means we all have RBF. If you actually had a smile while at complete rest, you’d look weird!
So it’s not a special problem to any single person, it’s just how muscles work. And there are plastic surgeons trying to capitalize on this insecurity by offering a surgery that makes the corners of the mouth upturned at rest. Don’t fall for it. Your face is fine.
If you feel like you can’t get rid of RBF when you’re wanting to, stop resting it! Put some tension in the right places when you’re out in public. This doesn’t mean grinning from ear to ear like a clown, it just means leaving a tiny bit of tension in the cheeks and corners of the mouth.
Be somewhat excited about your life or at least curious. Why? Because it’s really hard to flex those muscles when you’re uninterested, irritable, etc. It’ll come naturally if you’re noticing good things around you and thinking about people warmly.
And here’s a theory: tensing your face in a way that makes it look happier, actually trains you to BE happier. You become an upbeat person when you act like one and look like one.
Want another unfounded theory?
Smiling, laughing, or lightly flexing the happy muscles actually builds more muscle in and around the cheeks thereby changing the structure of your face. You can hypertrophy the muscles surrounding your cheekbones and in the process, give your face a more sculpted look. This is fantastic if you don’t have the genetics for good cheekbones. Just build muscle on top of what you do have.
Lifters are so used to hearing advice on keeping the core tense throughout the day or pulling the shoulders back. Neither of these things feel natural at first. But if you practice them, they get easier. Just like having a pleasant expression when you’re in public.
Do what you want. You can keep your RBF, just realize your face doesn’t have to be at rest 24 hours a day, it’s not uniquely ugly, and your thoughts actually do play a role in how it looks.
