Three Letters, Three Philosophies: The Asian Beauty Guide Worth Keeping by the Vanity

Elle has published a guide that separates I-Beauty, K-Beauty and J-Beauty, three of the most talked-about movements in Asian beauty, and looks at the rituals, ingredients and beliefs behind each one. It's for anyone who has seen those prefixes on a shelf in Beverly Hills or a bathroom counter in Palm Beach and wondered what actually sets them apart. The guide treats each as its own school of thought, with its own approach to the daily routine, rather than as passing trends. That's a welcome kind of precision for readers who like to know the house, the season and the reasoning behind whatever they put on.
