1. Cold Compress: Place the product in the refrigerator, and you can choose to refrigerate or freeze it according to the desired temperature (suggestion: 10 minutes or more). After taking it out, apply it to the area that needs cooling. When the temperature of the compress is close to the surface temperature, you can repeat the cooling process. It can be used repeatedly.

2. Heat Treatment: Place the product in the microwave, medium to low power, heat for 1-2 minutes, then apply it to the area that needs heat treatment (if it feels too hot, cool it down for a few minutes first). When the temperature feels close to the skin, you can reheat it. It can be used repeatedly.
