Yes, it can! The FOMI Care Ice eye mask uses a cold gel pad set into the eye mask that cools and reduces the puffiness around your eyes. They remain flexible after use and relieve stress, headaches, migraines, and fevers. This sleep mask can also reduce swelling. You can cool them down in a refrigerator or freezer but to a freezing temperature. Too low a temperature can damage your body tissues. The low temperature constricts your blood vessels which in turn can reduce inflammation and swelling.
