Glabridin is an isoflavonoid isolated from the roots of glycyrrhiza glabra (licorice root). Glabridin brightens by inhibiting activity of melanin-stimulating enzyme tyrosinase and dopachrome tautomerase (TRP-2). Glabridin is a multifunctional active that also posesses antioxidant and soothing anti-inflammatory activity.1 This unique combination of skills ensures efficient, effective brightening of skin’s appearance without irritation.2
