EXCLUSIVE AT NET-A-PORTER. Just as a HIIT workout tones and defines your body, FaceGym’s innovative mask has the equivalent effect on facial muscles, and you won’t even have to break a sweat. It uses electrical muscle stimulation technology to create a visibly lifted, firmed appearance from the comfort of your own home in just 10 minutes. Choose from one of the three programs that work to stimulate circulation, define the masseter muscle along the jaw and sculpt the zygomaticus major and minor muscles in the cheeks. The six intensity levels allow you to customize your routine, and the QR code links you to one of the brand’s trainers to help you get the most out of the device.
