If you are referring to the different gua sha techniques, it depends on what you're looking to do. If you want a basic facial massage, you would stroke your face upward and outward, as shown in diagram above. If you have pain (like around the temples or jaw) you can use a jiggle movement. That's where you place the gua sha stone against the tight muscle and then jiggle it to release the tension. See the technique tips here.
