Switch2Pure's Dual Sided Rose Quartz Crystal Facial Roller releases toxins from the skin with continued use. Smooth fine lines, wrinkles and naturally contour the cheekbones and jawline. Use the larger roller for the neck, chin, jawline, cheeks and forehead while the smaller roller can release tension or stress, specifically around the lips. Don't neglect the area between the brows! These rollers come with an amazing instructional diagram inside the box. Simply place the roller back in the box after each use so you can use the guide each time.
