Science
Mechanism of Action
This water-soluble botanical ingredient is rich in polyphenolic flavonoids (such as quercetin, quercitrin, hyperoside, and rutin), saponins, phenolic acids, and polysaccharides. Its mechanism involves robust anti-inflammatory effects through calming inflammatory cytokines and suppressing TNF-α pathways. It acts as an antioxidant by combating free radicals and aiding in skin repair. Furthermore, it possesses antibacterial/antimicrobial properties particularly effective against acne-causing Cutibacterium acnes. It functions as an astringent, helping to regulate sebum production and minimize pore appearance, while its polysaccharide content contributes humectant properties for enhanced skin hydration and moisture retention. Emerging research also indicates potential benefits in protecting against UVB damage and stimulating capillary circulation, thereby supporting improved skin immunity and regeneration.
