Bamboo Charcoal: Even more effective at drawing out pollutants are what's known as “activated” bamboo charcoal - charcoal that has been pulverized and steamed, giving it a wider surface area and thereby enabling it to absorb a higher volume of bacteria, toxins, and microparticles.
Activated charcoal - when used in a face mask - binds to dirt and helps pull it out of your pores, making them less visible (it's the oil and dirt that makes them appear bigger).
