Ingredient review
Cyperus Scariosus Root Oil
INCI: CYPERUS SCARIOSUS ROOT OIL
A fragrant root oil with a rich, earthy scent that may offer mild soothing benefits, but its use is primarily aromatic and can be irritating for sensitive skin.
In plain English
Cyperus Scariosus Root Oil is an essential oil pressed from the roots of a plant called Nagarmotha. It has a warm, woody, and slightly smoky smell that some people find grounding. In skincare, it is mainly added for its fragrance, though it also has a long history in traditional medicine for calming the skin. Because it is a concentrated essential oil, it can cause irritation if used in high amounts or on sensitive skin.

What it is
A natural essential oil obtained by steam distillation or solvent extraction of the dried roots of Cyperus scariosus, a perennial sedge native to India and other tropical regions.
How it works
When applied to the skin, the oil's volatile aromatic compounds interact with olfactory receptors, providing a sensory experience. Some of its constituents may have mild anti-inflammatory or antimicrobial properties, but these effects are not well-studied in cosmetic formulations.

In Ayurveda, Nagarmotha oil has been used to help calm minor skin irritations, though modern cosmetic evidence is limited.
Cons and cautions
Potential skin irritant
As a concentrated essential oil, it can cause redness, stinging, or allergic contact dermatitis, especially in high concentrations or on sensitive skin.
