About 20 years ago, researchers in Japan burned bamboo at high temperatures to create bamboo charcoal, which exhibited properties vastly different from the bamboo plant, including a high density and porous structure. Bamboo charcoal also has high mineral content such as calcium, potassium, sodium and iron. Over the years, many uses have been created for household to bedding and personal care.
The bamboo charcoal eye mask has the functions of releasing FIR (far infrared ray) and bringing anion. We can experience FIR energy as gentle, radiant heat, which can penetrate up to [3.5] inches beneath the skin. The eye mask could strengthen the immune system and stimulate blood circulation around eye area. It is efficient to relieve eye fatigue and stress.
