What it is
A combined extract from the aerial parts of Orostachys japonica and Saururus chinensis, two plants traditionally used in East Asian herbal medicine. The extract is typically prepared using water or alcohol solvents to pull out beneficial compounds like flavonoids and phenolic acids.
How it works
The extract delivers antioxidant compounds that can neutralize free radicals (unstable molecules that can damage skin cells). Some studies suggest it may also reduce the production of inflammatory signals in skin cells, leading to a mild calming effect. In a formula, it works alongside other ingredients to support the skin's natural defense systems.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without the irritation that some stronger antioxidants can cause.
Soothing potential
Early research indicates it may help calm minor redness or irritation, making it suitable for sensitive skin routines.
Cons and cautions
Limited evidence
Most studies are lab-based or on animals; there are few human clinical trials confirming its effectiveness in skincare.
Variable potency
As a natural extract, the concentration of active compounds can vary between batches, leading to inconsistent results.
Best for
- Anyone looking for gentle antioxidant support
- Those with sensitive or reactive skin who want a mild botanical ingredient
Use caution if
- Individuals with known allergies to either plant (uncommon)
