Science
Mechanism of Action
This polysaccharide functions as a potent antioxidant by neutralizing DPPH free radicals and reducing reactive oxygen species (ROS) induced by UVB exposure. It regulates melanogenesis by inhibiting tyrosinase activity and exerts immunomodulatory effects through the downregulation of inflammatory cytokines (such as IL-4 and IL-33) while promoting TGF-β1 to accelerate tissue repair and improve skin elasticity.

Key findings
- 01 In vitro testing demonstrated an 89% DPPH free radical scavenging rate at a concentration of 500µg/mL.
- 02 Comparative studies showed tyrosinase inhibition reaching up to 49%, performing at levels comparable to the brightening agent arbutin.
- 03 Bio-active assays indicate significant reductions in syncytia formation (66%) and suppression of atopic-associated cytokines in animal models.

Dusting Analysis
Due to its potency in small concentrations (as low as 0.1 μg/mL in some antiviral/cellular studies), it is often included at negligible levels purely for label claims. Effective skin barrier modulation typically requires higher inclusion rates.
The Formula
Formulation
Stability
Maintains structural integrity and gelling capacity most effectively in near-neutral environments; sensitive to extreme acidification.
