Dear RBF girl,
I empathize with you. Resting b*tch face syndrome is a daily problem in this world and I am sorry you may feel the same pain. No, we are not mad. It is JUST OUR FACE. With a mouth slightly frowned, eyebrows furrowed, and lips puckered, our natural look, doesn't look so natural.
We are perceived as grumpy, angry, cranky, moody, etc. no matter our true inner emotion. I have heard it all. Unfortunately, This caught-off-guard and expressionless face can deter those around you. You may be a nice person, but your face screams otherwise.
RBF has many pros and cons. While, yes, it can deter people from approaching you, this can come in handy when us ladies are at a bar and the last thing we want is a sloppy boy approaching us, trying to buy us a drink. Thank you, RBF shield. In a more negative sense, this can deflect potential friendships from interacting, as well. I have personally been told multiple times my RBF makes me look intimidating and unapproachable, when in fact they had no recognition of how nice I really am. Growing up, my mom always looked at me and said, "Quit frowning." I would then proceed to switch to a look of confusion as I was in a great mood, but my face naturally would prove otherwise. I guess you truly can't judge a book by its cover, especially if it's frowning.
Interestingly enough, this has become such an issue that many surgeons are receiving requests to surgically correct their "permafrown." With age, it is natural for gravity and genetics to droop the edges of our smile. As the mouth denotes such a large amount of our expression, it can shatter a person's approachability.
Fear not because you are not in this alone. Kanye West and Kristen Stewart have it much worse.
