From a science perspective, this skin spatula (love this term) uses high-frequency, ultrasonic oscillation technology and electrical muscle stimulation (EMS) to penetrate the skin. From a Mary perspective, IT JUST FEELS AMAZING (and is super effective). The Essia ultrasonic exfoliating spatula is used to essentially give yourself a spa-like facial every time you apply your skincare products. You can use it to exfoliate, moisturize and even lift. I really recommend watching this quick video to learn the proper way to use this incredibly effective tool, since it’s a pretty new approach. I’m in love with mine and I’m always delighted to discover new tech—especially of the skincare-focused variety. If you're interested, code MXWAND will get you 55% off!
