Glycyrrhiza glabra (liquorice root) extract is a botanical derivative valued for its skin-brightening and soothing properties, primarily due to compounds like glabridin and licochalcone A that inhibit tyrosinase and reduce inflammation. It is commonly used to address hyperpigmentation, redness, and irritation.
