Science
Mechanism of Action
The mechanism of action, as observed in the related *Ostrya carpinifolia L. Extract*, is attributed to its rich polyphenolic content, including myricitrin and quercitrin. This fraction effectively neutralizes reactive oxygen species, thereby mitigating oxidative stress. It also demonstrates anti-lipoxygenase activity to reduce inflammation, actively inhibits hyaluronidase to preserve hyaluronic acid, and prevents the degradation of collagen and elastin through anti-collagenase and anti-elastase actions. These combined effects contribute to anti-aging and robust anti-pollution defenses within the skin.

Formulation
Stability
Extraction typically utilizes hydroalcoholic solvents (e.g., EtOH/H2O 50/50 v/v), glycerin, and propylene glycol, indicating solubility in water and polar solvents. Due to potential viscosity, extracts may require transformation with liquid or solid supports like propylene glycol or maltodextrin for optimal integration into cosmetic formulations.
