Research on beauty apps in US and Europe

Looking for apps/ start ups in US and Europe, with 1M+ users/customers and/or funding up to series C or D. The apps of interest are beauty focused platforms where people share content only about beauty and fashion (say an instagram of beauty). Also looking for successful start ups which provide listings, offers, reviews of salons, gyms and beauty artists (e.g. make up artists, hair stylists, tattoo artists, dieticians, dermatologists etc.)
