What Is Imperata Cylindrica Root Extract?
Imperata Cylindrica Root Extract comes from the hardy cogon grass, a plant that grows in tropical and subtropical regions across Asia, Africa and Australia. The roots store high levels of potassium, starches and natural sugars that help the plant hold on to water in harsh climates. These same water loving molecules are what make the extract attractive for skincare.
Cogon grass has a long history in folk remedies for cooling and soothing the skin after minor irritations. As the cosmetics industry searched for gentle botanical hydrators in the late twentieth century formulators began studying the root and found it could boost skin moisture for hours. Today its use is backed by in-house studies showing improved hydration and a soft afterfeel.
To create the cosmetic grade ingredient manufacturers harvest the roots, wash and dry them then grind them into a coarse powder. The powder is soaked in a mixture of water or a skin friendly solvent like butylene glycol to pull out the active compounds. After steeping, the liquid is filtered, concentrated and standardized to ensure consistent levels of potassium and sugars before being preserved and shipped to formulators.
You will spot Imperata Cylindrica Root Extract in moisturizers, hydrating serums, sheet masks, after-sun lotions, long wear foundations and any product that claims all-day moisture or instant skin plumping.

Comedogenic Rating
Rating: 0/5
Imperata Cylindrica Root Extract is a water soluble humectant that contains no heavy oils or waxy lipids that could clog pores. Its main components are potassium, sugars and small starch molecules, all of which sit on the skin surface to bind moisture rather than settling into follicles. Because it is lightweight and non-greasy it is considered non-comedogenic.
Suitable for acne-prone or breakout-prone skin.
No special interactions with common acne treatments like benzoyl peroxide or salicylic acid have been reported.
Summary
Imperata Cylindrica Root Extract is primarily a skin conditioning agent that boosts hydration by drawing water to the skin and holding it there. This leaves the surface feeling softer, smoother and more comfortable for hours.
Although not as famous as hyaluronic acid or glycerin it appears in a growing number of moisturizers, serums and long wear makeup because formulators value its long lasting hydration and gentle profile.
Overall safety is excellent with only rare reports of irritation, mostly in people already sensitive to grasses. As with any new skincare product it is wise to perform a quick patch test before full use to make sure your skin agrees with it.
