Gua Sha is a natural alternative therapy that involves scraping your skin with a massage tool to improve your circulation. This ancient Chinese healing technique may offer a unique approach to better skin health. In Gua Sha, an esthetician scrapes you skin with short or long strokes to stimulate microcirculation of the soft tissue, which increases blood flow. They make these strokes with a smooth edged instrument know as a Gua Sha massage tool. The esthetician applies massage oil to you skin, and then uses the tool to repeatedly scrape your skin in a downward motion. Gua Sha is intended to address stagnant energy, called Chi, in the body that practitioners believe may be responsible for inflammation. Inflammation is the underlying cause in many diseases and conditions. Rubbing the skin’s surface is thought to help break up this energy, reduce inflammation and promote healing.
