Gua sha is a handheld tool marketed to use on the face to help improve blood and lymphatic circulation on the skin and help relieve tension in the facial muscles. Facial guy sha has been also marketed in the anti-aging sector of cosmetic industry, specifically to minimize fine lines and wrinkles and improving skin elasticity.
Initially utilized in traditional Chinese medicine was thought to promote the flow of “chi” or energy in the skin. Theoretically, the tool manufacturers claim that gliding the gun sha along the face will help break up the adhesions between the connective tissue between the muscle and the skin and help relieve muscle tension. Though may help with minimal puffiness of the skin, there is little to no evidence that it helps with skin contouring, collagen production and wrinkles. However, may be helpful when gently used to massage tense facial muscles.
