Licorice root extract (Glycyrrhiza glabra) is used in skincare for its anti-inflammatory and antioxidant properties, and its components (notably glabridin and liquiritin) can help reduce hyperpigmentation by inhibiting tyrosinase activity. It is commonly included to calm irritated skin and improve uneven skin tone.
