Why it's special? Ice Globes are safe to store in the freezer, we use only high-end durable borosilicate glass to minimize likelihood of glass breakage. Help relieve headaches, muscle tension, sinus pain and stress. The cooling massage will help you achieve relief and relaxation at home. How To Use? Place Ice Globes in the refrigerator (32-40°F or 0-4 °C) for 10 minutes prior to use. Glide globes over the face in a slow gentle motion, giving extra attention to any areas with inflammation or redness. Best results are seen when paired with a facial oil, serum, or hydrating mask. Repeat each movement 3-5 times for ice cold self-care.
