The beauty treatment "Gua Sha" originated in China. Gua Sha is a beauty method that uses a plate made of natural stone or a cow horn to scrape the skin, applying pressure to improve blood and lymphatic flow. By improving blood circulation and promoting the excretion of waste products, it can be expected to reduce swelling, slim the face, lift the skin, and boost metabolism. Gua Sha can be performed not only on the face but also on the whole body, and it is a beauty method that can be done at home. ※ Quoted from the internet
