Nano steam is a relatively recent technology that involves the generation of ultra-fine steam particles, typically much smaller than those created by traditional steam methods

A nanometer is one billionth of a meter, which is incredibly small because the particles are so small, they can penetrate the skin more easily than larger particles. the ultra-fine steam particles can soothe and hydrate the eyes more effectively. The steam helps to alleviate dryness and fatigue in the eyes, and the warm steam can also stimulate blood circulation around the eyes, helping to reduce puffiness and dark circles.
