Imperata Cylindrica Root Extract is a potassium-rich extract derived from the roots of Cogon grass. Its roots form a rhizome network, including 60% of the plant's mass. It contains starch and simple sugars and has been used in traditional Chinese medicine.
Imperata Cylindricais pyrophyte is a highly flammable plant and depends on fires for its ecological dominance, killing competing plants. It survives wildfires thanks to a rhizome network that accumulates considerable water and remains unaffected by the fire.
Due to its extraordinary water-retaining ability, Imperata Cylindrica Root Extract is used as the main active ingredient in Sederma's Moist 24™, which provides all-day-long moisturization. Cogon grass extract helps to draw moisture into skin cells, increasing the cytoplasm and allowing hydration to take place throughout the day.
In clinical studies with a preparation containing Imperata Cylindrica Root Extract, treated skin showed a 20% increase in hydration after 24 hours compared to a control.
