Cool Usage
Simply place in refrigerator or freezer until desired temperature for a cooling / ice pack effect. (usually placed in cold storage for 1-2 hours and the temperature of the mask depends on the time you take it out)
- Hot Usage
① Place the face mask into microwave oven (700W) for about 15-30 seconds (different heating time may be required for ovens of different wattage);
② Wrap face mask in a towel before placing onto affected area (e.g. strained muscles) to avoid burns due to the heat;
③ Repeat Step 1 when you feel that the mask has cooled and needs warming up.
