Science
Mechanism of Action
This ingredient operates through several key mechanisms. Laetiporus sulphureus extracts demonstrate robust antioxidant activity, likely mediated by polyphenolic compounds and polysaccharides, and can activate cellular antioxidant pathways such as Nrf2. Additionally, they exhibit selective antibacterial action against Gram-positive bacteria. Concurrently, Salvia plebeia extract contributes significant anti-inflammatory benefits by suppressing the production of pro-inflammatory cytokines like TNF-α, IL-6, and IL-8, alongside nitric oxide. Furthermore, the overall ferment filtrate functions as a humectant, attracting and retaining moisture in the skin.

Key findings
- 01 Research on Laetiporus sulphureus extract demonstrated significant antioxidant capacity, with DPPH free radical-scavenging activity reaching 86% inhibition at 800 µg/ml and 55% at 400 µg/ml. A specific concentration of 160 µg/ml yielded an 82.2% inhibition value, comparable to established antioxidants like BHA (96.4%) and α-tocopherol (98.6%).
- 02 In vitro and in vivo studies on Salvia plebeia ethanol extract revealed potent anti-inflammatory effects. It effectively inhibited the production of pro-inflammatory cytokines (TNF-α, IL-6, IL-8) and nitric oxide in LPS-stimulated cells. In an ovalbumin-induced mouse model, treatment with Salvia plebeia aerial parts extract notably reduced airway eosinophils, IL-4 and IL-13 levels, mucus production, and inflammatory infiltration, indicating comprehensive anti-inflammatory action.

Dusting Analysis
No available data suggests that this ingredient is commonly used at sub-efficacious 'dusting' concentrations, nor is there a known threshold percentage identified for minimal clinical efficacy of the combined ferment filtrate.
The Formula
Formulation
Stability
The ingredient is optimally stable and active within a pH range of 6.0 to 8.0, consistent with conditions favorable for Laetiporus sulphureus mycelial growth and water-based extract preparation.
Synergies
- The ingredient itself is a synergistic blend, combining distinct antioxidant, anti-inflammatory, and humectant properties from its fermented components.
Safety
Safety Profile
There are no specific safety assessments from regulatory bodies such as CIR, SCCS, or FDA for the combined LAETIPORUS SULPHUREUS MYCELIUM/SALVIA PLEBEIA EXTRACT FERMENT FILTRATE. While general assessments exist for other fermented ingredients, they do not directly address the safety profile of this particular combination.
