Science
Mechanism of Action
This extract operates through a synergistic blend of active compounds. Flavonoids and mucilage confer potent anti-inflammatory properties, effectively soothing irritation and diminishing redness. Flavonoids further offer significant antioxidant protection, neutralizing free radicals to mitigate premature aging and environmental damage. Mucilages and glycosides enhance skin hydration by binding water, thereby fortifying the skin barrier and promoting a soft, elastic texture. Tannins contribute an astringent effect, refining pores and toning the skin. Additionally, volatile oils and flavonoids exhibit antibacterial qualities, beneficial for blemish-prone skin. Its anti-aging efficacy is supported by enhanced skin cell metabolism and the inhibition of metalloproteinases and elastase, enzymes implicated in collagen degradation. Emerging data also suggests potential for tyrosinase inhibition, offering skin brightening effects, and photoprotective capabilities.
