Made with hypoallergenic glass and an anti-freeze liquid, these globes can be left in the fridge overnight or placed in the freezer for 20 minutes—tops. That said, they get cold quickly and work like a charm. You can use upwards motions to achieve a lifted look or drag the tools in a downward motion to help with lymphatic drainage and de-puffing. When all is said and done, just clean the ice globes with water and soap.
