licorice extract (Glycyrrhiza glabra) is considered an anti-irritant, studies indicate an ability to absorb uVA and uVB rays. Studies also conclude that licorice extract has a depigmenting effect as well as an inhibitory effect on melanin synthesis given its ability to act as a tyrosinase inhibitor. As a depigmenting agent, licorice extract is described as more effective than kojic acid and 75 times more effective than ascorbic acid. The chief constituent of licorice root is glycyrrhizin, present in concentrations that range from 5 to 24 percent depending on the variety of licorice used. A member of the bean family, licorice’s pharmacological properties are found in the plant’s roots and stem.
