Originally, Gua sha was used in Chinese medicine to move “negative energies”, which can also be described as the negative effects of stress or pain. When using Gua Sha, don’t use much pressure to move the stone and massage the face.
The idea here is more energetically moving it with the intrinsic properties of the stone and its shape, for more on the Gua Sha stone and how to use it at home, visit this blog: HERE
