Chinese Facial A gua sha is the main tool used in Chinese Facial, and is usually made of buffalo horn or jade. In Chinese herbal medicine, buffalo horn has a cold property and an acrid, salty flavor. Acridity is used to disperse and promote the circulation of qi and blood, as well as moistening and nourishing.

Facial gua sha moves lymphatic fluids, releases the fascia so skin can function better, and breaks down adhesions and hardness in muscles, like in the jaw.
