Science
Mechanism of Action
Ruscus Aculeatus Root Extract operates through a synergistic blend of active compounds, primarily ruscogenins, flavonoids, and saponins. Ruscogenins impart venotonic effects by promoting vein constriction and enhancing blood flow, thereby mitigating fluid pooling and associated puffiness, notably in delicate areas like under the eyes. Flavonoids deliver robust antioxidant protection and contribute to inflammation reduction, while saponins offer additional mild anti-inflammatory benefits. The extract also exhibits astringent qualities to minimize pore appearance and moderate sebum, further improving microcirculation to address concerns like dark circles. Its ability to act as a potent venous vasoconstrictor directly narrows blood vessels and reduces microvascular permeability, making it highly effective for visible redness.

Key findings
- 01 In a 2015 study, creams formulated with Ruscus aculeatus root extract achieved over a 60% reduction in redness severity scores in individuals with facial redness and rosacea after 4 weeks of use, significantly outperforming placebo groups which saw a 30% reduction.
- 02 A clinical study involving 166 women demonstrated that Ruscus aculeatus extract considerably reduced leg volume, ankle, and lower leg circumference, alongside alleviating subjective symptoms such as heaviness, tiredness, tension, and tingling in the legs.
- 03 In vitro investigations indicate that topical application of Ruscus extract leads to a dose-dependent inhibition of histamine's macromolecular permeability-increasing effect, suggesting anti-inflammatory action.
- 04 An in vitro study confirmed that Ruscus aculeatus root extract exhibited antioxidant activity when applied to human skin cells.
