Antioxidant Skin conditioning Soothing Brightening Collagen protection

Science

Mechanism of Action

This extract utilizes a multi-pathway approach to skin health: it inhibits tyrosinase activity through its natural arbutin and gallic acid content to prevent melanin synthesis, while simultaneously acting as a powerful antioxidant by scavenging DPPH/ABTS radicals and chelating Fe2+ ions. Furthermore, its triterpene profile provides anti-inflammatory support and protects structural collagen by significantly reducing reactive oxygen species (ROS) levels within dermal cells.

Stability

The extract's polysaccharides are highly stable in water, though hydro-alcoholic or glycolic bases are preferred for triterpene stability. Formulators must avoid alkaline environments to prevent the degradation of its arbutin content.
