Science
Mechanism of Action
Sparassis latifolia powder exerts its beneficial effects primarily through its potent antioxidant and immune-modulating components. It actively neutralizes free radicals, thereby mitigating oxidative stress. Its polysaccharides regulate immune function via TLR4-mediated MyD88-dependent and -independent signaling pathways in macrophages, enhancing cellular proliferation and the release of protective cytokines such as nitric oxide, TNF-α, IL-6, and IFN-β. Furthermore, extracts from the closely related species, Sparassis crispa, have demonstrated the ability to significantly upregulate HAS1, HAS2, and HAS3 gene expression, leading to increased endogenous hyaluronic acid synthesis. This mechanism translates to enhanced skin moisture, improved elasticity, and reduced wrinkle appearance. The ingredient also contributes to skin barrier strengthening, soothing inflammation, reducing sensitivity, and exhibiting antibacterial activities.
