Gua Sha is a traditional Chinese facial tool used to massage your skin and improve circulation. The unique shape of a Gua Sha enables it to perfectly contour to your face. Use a medium pressure to scrape the Gua Sha across your face to smooth fine lines, lift eyebrows, firm your face and reduce puffiness. If you suffer from headaches, stroking a Gua Sha over your temples can help to alleviate the pain. A Gua Sha can also be used on other areas of your body, like legs, neck and back to relieve muscle pain and tension.
