When it comes to beauty, there’s no one-size-fits-all—which is why L’Oréal created the Perso, a smart dispenser that blends lipstick, foundation and skin-care formulas tailored to individual users. Simply log on to the device’s app and upload a selfie, which the app’s algorithm will evaluate for common skin concerns like dark spots, wrinkles and blemishes. For skin-care formulas, the app will also factor in environmental condi- tions like humidity and sun exposure before the product requested by the user is mixed and dispensed from the device. The Perso, which will debut in 2021 for $200 to $300, uses interchangeable cartridges to blend its products, meaning users can toggle with ease between mixing either skin care or makeup. —Cady Lang
