Science

Utilizing a two-stage fermentation by Aspergillus and Lactobacillus, the plant's complex polysaccharides are enzymatically broken down into smaller molecules, including Astragaloside IV and organic acids. These metabolites stimulate endogenous hyaluronic acid production, suppress tyrosinase to brighten the complexion, and neutralize oxidative stress through enriched flavonoid content.
