Beloved British beauty journalist Sali Hughes visited the ELLE Canada Closet to explain the intriguing backstories to five of the more than 200 game-changing beauty products in her new book, “Pretty Iconic: A Personal Look at the Beauty Products that Changed the World,” available now. Below, she explains that strobing was not – contrary to popular belief – created on Instagram, how Estée Lauder basically invented the anti-aging serum category, the surprising demographic Benetint was designed for and the proper way to use YSL Touche Éclat (because everyone is still doing it wrong). 

Beauty enthusiasts, get comfortable.
