A jade roller is a skincare tool made from jade stone, traditionally used in Chinese beauty practices. It typically features a handle with a larger roller on one end and a smaller roller on the other. The larger roller is designed for use on the face, while the smaller one is often used around the eyes. Using a jade roller is believed to promote lymphatic drainage, reduce puffiness, and improve blood circulation. Many people also use it to enhance the absorption of serums and moisturizers during their skincare routine. The cooling effect of the jade stone can provide a soothing sensation on the skin.
