Jade face rollers are ancient Chinese beauty tools that stimulate blood flow and improve facial appearance. They work by rolling the stone over the skin to relax facial muscles, increase oxygenation, and reduce fine lines and wrinkles. Regular use can also help with lymphatic drainage, break down blackheads, and smooth out uneven surfaces. To get the most from jade face rollers, one should be gentle, breathe deeply, and target specific areas of the face.
