Facial rollers are skincare tools typically made from materials like jade or rose quartz. They consist of a handle with a rolling stone at one or both ends. Users gently roll the stone over their face to promote circulation, reduce puffiness, and enhance the absorption of skincare products. Many people believe that facial rollers can help with lymphatic drainage and provide a cooling effect, making them a popular addition to beauty routines. While some studies suggest potential benefits, scientific evidence is limited, and results can vary from person to person.
