Science
Mechanism of Action
This extract operates through a multi-pathway approach: it inhibits NF-kappaB signaling to reduce inflammatory cytokines and employs a potent array of flavonoids (quercetin, rutin, and kaempferol) to scavenge free radicals. Its natural saponin and tannin content provides mild antimicrobial benefits and structural support for the skin's moisture barrier.

Dusting Analysis
Due to its complex phytochemical profile, many brands include it at sub-functional levels (<0.1%) merely for label claims. To achieve measurable anti-inflammatory and antioxidant benefits, concentrations should ideally align with levels used in efficacy studies.
