As a treatment in traditional Chinese medicine, gua sha utilizes a solution (face oil or water) and a smooth material (jade plates, metal plates, etc) to stimulate a specific area of the body.
- Promote blood circulation. “From a Chinese medicine perspective, the Tai Yin meridians (composed of the lung and spleen) and Yang Ming meridians (composed of the large intestines and the stomach) are responsible for your skin's overall health,” said Lee. “When you gently scrape the skin on your face with your gua sha tool, what you are doing is stimulating your Yang Ming meridians. You are also sending your body a signal that this area needs more blood circulation.”
- Improve fine lines and wrinkles. Gua sha “can temporarily improve the appearance for the newly and very gentle ones,” Wang said. However, she noted that “for long-standing wrinkles, gua sha should not be the first choice.”
- Promotes lymphatic drainage. Gua sha can eliminate fluid build-up, which can in turn reduce puffiness, experts said.
- Relieves tension from muscles. Experts noted that by applying pressure with a gua sha tool regularly, users can untangle knotted areas and release built-up muscular tension.
