Liquorice is a legume which grows in the Mediterranean, the Middle East & Russia. It contains the active constituent glabridin, which has been shown to prevent and reverse UV-induced skin damage, to provide visible skin-lightening properties to the skin.

Its second active component, Glycyrrhetinic acid is used in skincare for its anti-inflammatory benefits. It works by inhibiting the production of inflammatory substances, such as cortisone, within the body, with some research showing results to be comparable to prescription hydrocortisone cream.
