Science
Mechanism of Action
This extract functions primarily through its rich content of usnic acid and phenolic compounds. Usnic acid provides antibacterial action by inhibiting protein synthesis and altering cell membranes, effectively combating various pathogens. Both usnic acid and other phenolic secondary chemicals deliver robust antioxidant effects, shielding skin cells from oxidative stress and premature aging. Additionally, it reduces inflammation by inhibiting NF-κB and inflammasome pathways, promoting skin repair and cellular protection.

Key findings
- 01 Studies indicate a reduction in oxidative stress levels in fibroblasts at concentrations as low as 0.01%, demonstrating non-cytotoxicity at 0.01% and 0.1%.
- 02 For comprehensive benefits including broad-spectrum antimicrobial activity, antioxidant properties, anti-inflammatory effects, wound healing, and cytoprotective action, usage levels from 1.0% to 4.0% are recommended.

The Formula
Formulation
Stability
Water-soluble forms (e.g., in 2,3-Butanediol) are non-ionic and should be incorporated into aqueous systems or the aqueous phase of emulsions at temperatures of 25°C (77°F) or below, maintaining a formulation pH between 3 and 8 to prevent darkening and ensure stability. Prolonged exposure to UV light and temperatures above 25°C should be avoided. Liposoluble forms (e.g., in Triethyl Citrate) are heat-stable and can be added to the lipid phase or surfactant system at 40-60°C or at room temperature during the final stage with proper dispersion.
Safety
Safety Profile
Formal safety assessments by CIR, SCCS, or FDA are currently unavailable. However, non-cytotoxicity has been confirmed at concentrations of 0.01% and 0.1%. Furthermore, formulations featuring this extract are COSMOS-certified and reported to be gentle and well-tolerated, even by sensitive skin.
