Science

Phaseolus Angularis Seed Starch operates on multiple levels. As a powder, it provides gentle physical exfoliation, aiding in the removal of dead skin cells and deep cleansing of pores, which can reduce congestion and surface shine. Beyond its physical properties, the extract component exhibits significant antioxidant activity by efficiently scavenging reactive oxygen species (ROS), with studies demonstrating a 63.2% reduction in ROS levels at a concentration of 100 µg/mL. It actively combats photoaging by downregulating critical matrix metalloproteinases (MMP-1 and MMP-3), simultaneously boosting procollagen type I production for improved skin structural integrity. This ingredient also supports skin hydration, enhances elasticity, and contributes to reducing inflammation, promoting overall skin balance and a brighter complexion.
