Science

Mechanism of Action

This extract operates through multiple pathways to support and rejuvenate the skin. It effectively functions as an antioxidant, mitigating cellular damage by reducing UVB-induced reactive oxygen species (ROS). It reinforces the skin's natural protective barrier, thereby locking in moisture, preventing dryness, and promoting a soft, smooth, and hydrated complexion. Its inherent anti-inflammatory properties help to calm irritation and reduce skin redness. Furthermore, the extract offers robust protection against photoaging by encouraging the production of vital dermal components such as type I collagen, elastin, and hyaluronic acid synthase (HAS1, HAS2), as well as filaggrin, which collectively improve barrier function and hydration. It also downregulates the activity of matrix metalloproteinases (MMP-1, MMP-3, MMP-9), enzymes responsible for collagen degradation, and modulates the MAPK/AP-1 and TGFβ-Smad pathways, crucial for collagen synthesis and overall skin renewal, contributing to a more radiant appearance.
