Glycyrrhiza Glabra (licorice) Root Extract is a botanical ingredient containing glycyrrhizin and glabridin, valued for its anti-inflammatory and skin-brightening properties. It is commonly used to calm irritation, reduce redness, and help fade hyperpigmentation by inhibiting tyrosinase activity.

Allergic contact dermatitis | Rare | Sensitization to licorice constituents has been reported in isolated cases. |
Cross-reactivity in those with plant/legume allergies | Very rare | Licorice belongs to the Fabaceae family; theoretical cross-sensitivity is rarely documented topically. |
