Bamboos are evergreen perennial flowering plants in the subfamily Bambusoideae that include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system.

Some bamboo species are known to exudate natural silica.
Microzest 25 Bamboo is manufactured by micronization of dried bamboo sap composed at more than 75% of organic silica well known to absorb the sebum.

This very fine powder (less than 25 microns) obtained by micronization of silica concretions contained in bamboo, absorbs sebum and sweat and mattifies skin. The skin is less oily, softer and shiny, its smell is diminished. 

It is recommended for oily and acne-prone skin care products, deodorants and antiperspirants, makeup, dry shampoo, talcum powder, toothpaste.
