Antioxidant effects

As discussed in the assay performed to test the inhibition of superoxide production by glabridin, it can be said that glabridin has an antioxidant effect in addition to its skin-whitening (anti-melanogenetic) and anti-inflammatory properties.

Licorice used topically is documented to reduce the amount of corticosteroids in dermatological infections. This is probably by inhibiting     11-β hydroxysteroid dehydrogenase which is responsible for the conversion of cortisol to corticosterone and thus, potentiating the effects of steroids.
