Gua sha stones are smooth, flat tools traditionally used in Chinese medicine for a technique called gua sha. This practice involves scraping the skin to promote circulation, relieve muscle tension, and enhance overall wellness. Gua sha stones are typically made from materials like jade or rose quartz, which are believed to have healing properties. The stones come in various shapes and sizes, designed to fit different areas of the body, including the face. Many people use gua sha stones as part of their skincare routine, claiming they help reduce puffiness and improve skin texture.
