Science
Mechanism of Action
The extract operates through a dual-action pathway: it physiologically upregulates Aquaporin-3 water channels and Filaggrin proteins to improve internal cellular hydration while simultaneously forming a physical polysaccharide film that significantly reduces transepidermal water loss (TEWL). Furthermore, it provides secondary benefits by suppressing inflammatory markers (IL-6 and TNF-alpha) and boosting natural antioxidant enzymes like Superoxide Dismutase.
Research
Clinical Evidence
High confidence0.74%
Key findings
- 01 Demonstrated optimal efficacy at 0.74% in film-forming spray applications for TEWL reduction and hydration.
- 02 In vitro analysis confirmed cellular hydration via increased AQP3 and FLG expression at concentrations ranging from 37.5 to 300 µg/mL.
- 03 Significant antioxidant activity (77.5% radical scavenging) noted at 10 mg/mL concentrations.
Transparency
Dusting Analysis
Because it is a botanical extract with a high molecular weight polysaccharide profile, it is often included at 'label claim' levels (under 0.1%). To achieve the clinically validated film-forming and barrier-strengthening effects, it should ideally be formulated near the 0.74% mark.

Formulation
Stability
Peak stability is achieved at a neutral pH of 7.0. The integrity of the polysaccharide gel structure and overall viscosity may degrade in highly acidic (pH < 4.0) or strongly alkaline environments.

Safety
Safety Profile
While not yet formally reviewed by the CIR, its long-standing status as an edible mushroom and its use in 'Teen Safe' hypoallergenic products suggest an excellent safety profile for topical use.
