When it comes to the lives, routines, and product collections of makeup artists, we’re intrigued—or, to be more accurate, entranced. After all, these are the artistic professionals who spend their days and nights prepping all of the industry’s most fabulous names for fashion shows, editorial shoots, red carpets, film sets, ad campaigns, and so, so much more. Not only do they have access to the world’s most beautiful faces any given day, but they also have access to the world’s most covetable skincare and makeup products. A safe assumption? They know what’s what within the beauty product realm and only use the crème de la crème formulas, colors, and brands. Not only on their A-list clients, mind you, but on their own faces as well.
