Licorice root extract is a botanical ingredient valued for its content of glabridin, liquiritin and glycyrrhizinic acid, which inhibit tyrosinase to reduce hyperpigmentation and provide soothing, anti-inflammatory and antioxidant effects. It is commonly used to address uneven skin tone, redness and signs of irritation.
