Science
Mechanism of Action
This multifaceted extract exerts its effects primarily through its rich composition of polyphenols and flavonoids, including catechin, epicatechin, quercetin, and apigenin, which effectively scavenge free radicals and mitigate oxidative stress at a cellular level. It enhances skin hydration by improving moisture retention, leading to a softer, more nourished complexion. The extract exhibits targeted antimicrobial activity against various pathogenic bacteria, promoting clearer skin. Furthermore, specific components like pinhão seed lectins contribute anti-inflammatory effects, and its antigenotoxic properties offer crucial protection against DNA damage caused by external factors.
