New book taps into the cultural history of eyeliner

For centuries, eyeliner has been seen as a staple, and often the only beauty item some women and men wear. In culture journalist Zahra Hankir's latest book, "Eyeliner: A Cultural History," readers learn how eyeliner isn't just some superficial beauty hack and that in many cultures around the world, it has been revolutionized and popularized by people of color for medicinal purposes, authority and its cultural ties.
