Cold application: Cool the compress for 2 hours in the cooling or freezer compartment of your refrigerator (max. -18°C) prior to use. The compress may be kept in the freezer after use, so that it will always be ready when needed.
Hot application: Place the compress in hot water (up to 80°C) for about 4 minutes or heat up in a microwave oven (2 minutes at 280 W). Keep a constant eye on the compress while heating it. Heating may be prolonged in intervals of 10 seconds. Overheating might destroy the compress. After heating the compress, handle with care and touch with a towel to protect yourself from skin burns. Knead the compress thoroughly after each heating process to ensure even heat distribution.
Wrap a towel or similar around the compress and place onto your skin as needed.
