Our Gua Sha stone is imported from Brazil and crafted in Tucson, AZ. Each tool includes an instruction card and velvet-like storage pouch. Gua Sha is an ancient technique from Chinese medicine that involves massaging the face in a “scraping” motion to improve your complexion. The theory behind Gua Sha is that it increases blood flow and lymphatic circulation, which may smooth the appearance of wrinkles, brighten complexion, improve skin tone and texture and firm the skin.
