Gua sha is a traditional Chinese healing method in which a trained professional uses a smooth-edged tool to stroke your skin while they press on it. This motion raises small, red, rash-like dots that show under your skin called petechiae. It has been proven to help relieve tension in the face, reduce puffiness and inflammation, and it can even help reduce sinus pressure. It is recommended to follow the practice of facial Gua Sha at least thrice a week to maintain results.
