Glycyrrhiza Glabra (licorice) root extract is a botanical ingredient valued for its skin-brightening and anti-inflammatory properties, primarily due to glabridin and licochalcone A, which inhibit tyrosinase activity and reduce redness. It is commonly used to address hyperpigmentation, uneven tone, and irritation in topical formulations.

| Allergic contact dermatitis | Rare | Reported in individuals sensitized to licorice or related botanicals. |
| Redness or burning sensation | Rare | Typically associated with higher concentrations or pre-existing sensitivity. |
