Science
Mechanism of Action
This extract operates through a synergistic blend of kaempferol and quercetin glycosides alongside water-soluble polysaccharides (BTp1). It neutralizes reactive oxygen species (ROS) via NF-κB and Nrf2 pathway modulation, suppresses Th2-type immune responses to soothe dermatitis, and acts as a targeted tyrosinase inhibitor to interrupt the melanogenesis cycle.

Key findings
- 01 Demonstrated heavy metal chelation and fine dust protection in South Korean Patent KR101786861B1.
- 02 In vivo attenuation of contact dermatitis via Th2-type immune response inhibition (Journal of Dermatological Science, 2015).
- 03 Dose-dependent inhibition of melanin synthesis and tyrosinase activity at concentrations of 1.0-5.0% (Korean Patent KR-20130099610-A).
Transparency
Dusting Analysis
While this extract shows antioxidant potential at very low levels, clinical efficacy for brightening and anti-pollution benefits requires concentrations between 0.1% and 5.0%. Formulations including it below 0.1% are typically utilizing the ingredient for label claims rather than physiological impact.
The Formula
Formulation
Stability
The extract contains both water-soluble and oil-soluble fractions; it is stable in emulsions but requires cold-processing (avoiding high heat) to preserve the integrity of its bioactive flavonoids and polysaccharides.
Synergies
- Niacinamide
- Ascorbic Acid
