Gua sha, also known as kerokan or coining is part of traditional Chinese medicine. This alternative therapy involves rubbing the skin with a special massage tool to improve circulation and chronic pain.

The most common do-it-yourself treatment is focused on the face because it involves more gentle techniques than those used by a practitioner. People who practice gua sha daily may see results such as improved circulation, reduced wrinkles, improved skin tone and pigmentation, a more defined jawline, decongested sinuses and less puffy eyes. There is also the benefit of tension release. A natural stone is the most recommended material and the application of facial oil before use will ensure the stone glides easily across the skin.

Personal research before use is recommended. This technique should not be used in the presence of certain medical conditions.
