Spectacular. Luckily, Snopes can’t confirm: https://www.snopes.com/fact-check/justin-trudeaus-eyebrow/
Has the world lost all sense? His eyebrow didn't come off. There is other video taken at the exact same time. It's a matter of lighting, he has weird eyebrows that a re thicker at the bottom. Look at more pictures of him.
his makeup folk decided to try and make his face look more serious by cutting his eyebrows at an angle and messed up. His normal eyebrow height would make it appear he is always asking a question, and less serious.
My grandma, a very partisan republican, brought this up laughing and I responded with "as opposed to Trump who goes out of his way to cultivate an entirely natural look." I hate to play the inverse of the "but but but Obama Hillary Benghazi rabble rabble" but couldn't pass that up. She had no response.
