For Heat Therapy
Place the compress in the microwave. Heat in 30-second increments until desired warmth is achieved but no longer than 1.5 minutes. Always test the temperature of your mask before applying it to your skin. 

For Cold Therapy
Store in the freezer until you are ready to use it. The mask can be stored in the freezer in between uses indefinitely. If you plan to heat a mask that has been stored in the freezer, allow the mask to come to room temperature before heating it in the microwave.
