Steam Eye Mask

Basic Principle

The mask contains heat-generating materials such as iron powder, activated carbon, and water-absorbent resin. Upon opening the package, these materials react with oxygen in the air (similar to the mechanism of disposable heat packs), continuously releasing warm water vapor. The temperature generally stays around 40°C for approximately 20–30 minutes.

Key Benefits

Relieves eye strain:The warmth promotes blood circulation around the eyes and relaxes eye muscles; it is ideal for use after prolonged periods of eye strain (such as screen time or studying).

Aids sleep:The combination of warmth and light-blocking helps relax both body and mind, making it a popular choice for sleep support.

Alleviates dryness:The water vapor provides a mild moisturizing effect for the eyes (though this effect is limited and cannot replace medical treatment for dry eye syndrome).
