Science
Mechanism of Action
This plant extract functions by delivering powerful antioxidant compounds to the skin, most notably resveratrol, which is well-documented for its ability to neutralize reactive oxygen species (ROS). While direct human skin studies are limited, in vitro research on isolated compounds from *R. sachalinensis* demonstrates neuroprotective effects correlated with this robust antioxidant activity.

Stability
The active components within the extract, including emodin, physcion, and resveratrol, typically exhibit higher solubility in organic solvents. The extract's water solubility is not precisely quantified but appears to be low. General flavonoid stability suggests optimal conditions at room temperature, protected from light, within a pH range of 1.2 to 7.4.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) and SCCS have not yet published an opinion on Reynoutria Sachalinensis Extract for cosmetic use. However, assessments by Canadian regulatory bodies for its biopesticide applications indicate low acute toxicity via oral, dermal, and inhalation routes, with minimal skin irritation and no dermal sensitization observed for the technical grade active ingredient. Its historical use in traditional medicine and as a food ingredient further suggests a low risk of systemic toxicity.
