BUXUS SEMPERVIRENS LEAF EXTRACT.

Valuable CAS 84012-17-9 / SKIN CONDITIONING

A botanical extract derived from boxwood leaves that delivers multifaceted skin benefits through its unique alkaloid and flavonoid profile. This extract demonstrates remarkable cellular regulation properties by modulating autophagy—the skin's natural detoxification process—while providing antioxidant protection against environmental stressors. Its gentle yet effective action makes it suitable across all skin types, particularly valuable for addressing hyperproliferative conditions and supporting overall skin health.

soothing antioxidant antimicrobial/antibacterial

Science

Functions through multiple pathways including ROS scavenging via flavonoids and tannins, cellular autophagy modulation through steroidal alkaloids (buxine, cyclobuxine), and inflammatory pathway inhibition. The extract promotes cellular detoxification and renewal by enhancing autophagic flow in skin fibroblasts, while simultaneously providing antimicrobial protection against various pathogens.
