Science
Mechanism of Action
Through a controlled fermentation process utilizing Lactobacillus lactis, Eriodictyon californicum leaves are transformed, yielding beneficial glycoproteins. These glycoproteins function as potent humectants, drawing and retaining water in the skin via hydrogen bonding, thereby significantly enhancing hydration. Furthermore, the extract delivers soothing properties, improves skin's emollient feel, reduces tackiness, and contributes a smooth texture. The inherent phenols and flavonoids from the Yerba Santa plant also confer antioxidant protection.

Key findings
- 01 While specific clinical efficacy studies on the fermented extract at defined concentrations are limited, research on a non-fermented ethanol extract of Eriodictyon californicum leaves demonstrated significant antioxidant capabilities, showing 93.39% inhibition of DPPH radicals, 57.36% inhibition of superoxide radicals, and 80.89% inhibition of hydroxyl radicals. This highlights the foundational antioxidant potential of the source plant. A suggested formulation use level for the fermented extract is typically 1.0-5.0%.
