L’Oréal, the leading global cosmetics company, harnessed advanced technologies like Augmented Reality (AR) and Artificial Intelligence (AI) to innovate personalized beauty experiences. After acquiring ModiFace, a leader in AR and AI for beauty, L’Oréal launched the StyleMyHair app for virtual hair try-ons and Vichy SkinConsult AI for personalized skin diagnostics. The company also introduced Perso, an AI-powered device that creates custom skincare formulas based on local environmental data. Collaborations with Google Lens and Amazon enhance both in-store and online shopping experiences through virtual try-on technology. Additionally, L’Oréal's sustainability efforts include makeup recycling bins across UK stores, promoted through location-based services. These initiatives demonstrate L’Oréal’s commitment to blending technology with beauty to enhance customer engagement, personalization, and sustainability.
