Imperata Cylindrica Root Extract

Also-called-like-this: Cogon Grass Root Extract, Japanese Bloodgrass Root Extract
What-it-does: moisturizer/humectant


A subtropical plant that thrives in flooded environments and is claimed to give excellent long-term moisturizing effects. Its hydrating ability is due to the chemical composition of the rhizomes that contain natural osmoprotective compounds such as 3-dimethylsulfoniopropionate (DMSP), potassium, starches, and sugars. 

Osmoprotective compounds are interesting, skincare-wise, as they are thought to be able to increase intracellular osmosis, meaning water is drawn into the skin cells. According to the efficacy data from the manufacturer, 2% of ABS Imperata Cylindrica Extract (the trade name of the diluted version of the root extract) is able to increase the level of skin moisturization by almost 45%, which is 88% more effective than the untreated control. 

This all sounds great, however, in terms of comparative effectiveness, Imperata Cylindrica came up somewhat short in the study published in the Journal of cosmetic dermatology. They compared four hydrogels with different moisturizer actives and although all the formulas did hydrate the skin, the one with Imperata Cylindrica extract performed less well than the same formula with urea or sugar-based hydrating trio, called Aquaxyl

Still, it is a skin goodie with nice moisturizing properties, so if you are after skin hydration, it is a good one to spot on the INCI list. 

Show me some proof
