We're sorry, but the OPTASE® Moist Heat Mask is designed for microwave heating only, so it can't be heated in an oven or steamer.
Before you heat it up, please make sure your microwave and turntable are clean from dirt and greace and dry. Place the OPTASE® Moist Heat Mask flat in the centre of the turntable, ensuring it can rotate freely for even heating.
If your microwave has a metal tray instead of a turntable, please use a microwavable plate to place the Moist Heat Mask on before heating. Avoid placing the mask directly on the metal surface, as this could cause burning or damage. The microwavable plate acts as a safe barrier.
For an 800W microwave, heat the OPTASE® Moist Heat Mask for 25 seconds. Always test the temperature by touching the mask before applying it to closed eyes. If needed, allow it to cool for a minute and test again.
Please don’t leave the OPTASE® Moist Heat Mask unattended while it’s in the microwave. After heating, it might look moist, but your skin shouldn't feel damp when you apply it. Wipe it with a damp cloth (but don’t soak it), and let it air dry for at least 24 hours before using it again. Remember to check your OPTASE® Moist Heat Mask regularly and replace it if it shows any signs of wear or damage.
