What it is
An extract obtained from the dried roots of Cyperus scariosus, a perennial sedge plant native to India and parts of Asia. The extract contains compounds like flavonoids, terpenoids, and essential oils that contribute to its antioxidant and anti-inflammatory activity.
How it works
The antioxidant compounds in the extract help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. By reducing oxidative stress, the extract may help protect collagen and elastin fibers. Its anti-inflammatory properties can also help calm minor redness or irritation when applied topically.
Pros
Gentle antioxidant
Provides a mild layer of protection against free radicals without the irritation that some stronger antioxidants can cause.
Soothing potential
May help reduce minor redness or sensitivity, making it suitable for reactive skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; there are few well-controlled human trials on its skincare benefits.
Batch variability
As a natural extract, the concentration of active compounds can differ between batches, leading to inconsistent results.
Best for
- Anyone looking for gentle antioxidant support
- People with normal to combination skin who enjoy botanical ingredients
Use caution if
- Individuals with known allergies to sedge plants or essential oils
- Those seeking clinically proven, high-efficacy antioxidants like vitamin C or ferulic acid
