Science
Mechanism of Action
This extract operates through a multi-pronged mechanism. Its key component, Glycyrrhizin, exerts potent anti-inflammatory and anti-allergic effects by stimulating endogenous anti-inflammatory processes and suppressing pro-inflammatory cytokines, alongside inhibiting COX-2 and iNOS. Antioxidant activity is provided by flavonoids and phenolic compounds, which effectively neutralize free radicals and protect skin from oxidative damage. Furthermore, Glabridin and liquiritin, often present in licorice extracts, target tyrosinase activity to reduce melanin production, thereby diminishing hyperpigmentation and enhancing overall skin radiance.

The Formula
Formulation
Stability
This extract demonstrates versatility in formulation, being soluble in both water and alcoholic solvents (e.g., methanol). While a specific optimal pH range for the stability of the entire Glycyrrhiza Glabra Callus Culture Extract is not explicitly defined, Glycyrrhizin, a major active component, exhibits high thermal stability (100°C-121°C) and broad pH stability (4.5-9.5). For Glycyrrhiza Glabra Root Extract, water solubility and a pH range of 3.5-5.5 have been reported, suggesting potential compatibility within typical cosmetic formulation pH ranges.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that all licorice-derived ingredients, including Glycyrrhiza Glabra (Licorice) Root Extract, are safe for use in cosmetics. Licorice (Glycyrrhiza spp.) is also listed by the FDA as Generally Recognized as Safe (GRAS) for direct food consumption. While generally considered safe for topical application, individuals with known licorice allergies or particularly sensitive skin should exercise caution, as rare instances of skin irritation, allergic reactions, or contact dermatitis have been reported.
