Glitter Love are reusable pads for the eye contour with cold or hot effect that will recover the brightness of your eyes instantly. These little hearts full of love will immediately eliminate puffiness and dark circles and restore your eyes to their natural look. Before heating or cooling Glitter Love make sure that the gel inside is evenly distributed. Check that the temperature is adequate before application, especially at the edges of the cores. Cold effect: Keep in the refrigerator or freezer for at least 2 hours before applying to the face. Heat effect: Heat in the microwave in 10-second intervals until the desired temperature is reached, rotating the cores to obtain a uniform temperature on each side.
