Use Tips: Apply oil or serum to face and neck area, then gently roll from the center of your neck outwards. Continue rolling from the center of the face, first at the jawline, then cheekbones, under eyes, and forehead outwards and upwards toward the hairline. Go over each area several times. The larger roller is intended for your face and neck while the smaller roller is made for more delicate areas around the eyes and nose. Store the roller in the refrigerator to enhance the cooling effect.
