Liquorice (Glycyrrhiza glabra) root extract is used in skincare for its skin-brightening and anti-inflammatory properties, primarily attributed to compounds like glabridin and liquiritin that inhibit tyrosinase and soothe irritation. It is commonly included to address hyperpigmentation, redness, and uneven skin tone.
