Science
Mechanism of Action
This botanical extract functions through a dual-action pathway: it regulates the sebaceous glands to moderate excess oil production (antiseborrhoeic activity) while its rich profile of flavonoids and saponins neutralizes free radicals. Additionally, its high mineral content—specifically magnesium, calcium, and potassium—helps maintain the skin's osmotic pressure and reinforces the structural integrity of the moisture barrier.

Clinical Evidence

Key findings
- 01 In-vitro analysis demonstrated a 67.3% inhibition of Monoamine Oxidase B (MAO-B) at a concentration of 20µg/150µL, suggesting significant neuroprotective and antioxidant properties.
- 02 Commercial clinical evaluations confirm that concentrations between 1.0% and 5.0% provide measurable antiseborrhoeic benefits, effectively reducing skin oiliness and balancing sebum output.
Transparency
Dusting Analysis
Because it is often supplied in a diluted liquid base (glycerin or glycol), brands may include it at fractional percentages (under 1%) for marketing claims. To achieve the sebaceous regulation seen in clinical data, a minimum inclusion of 1.0% is required.
The Formula
Formulation
Stability
Heat-sensitive due to its antioxidant content; it must be incorporated during the cool-down phase (below 40°C) of the formulation process. Stable within standard physiological pH ranges.
