Licorice root (Glycyrrhiza glabra) contains glycyrrhizin and flavonoids which have soothing, anti-inflammatory, and mild skin-brightening effects. Studies show licorice’s compounds can inhibit melanin production and calm inflammation, making it useful for hyperpigmentation and redness.

Traditional use includes throat-soothing teas and digestive support. Externally, it’s added to masks or serums to hydrate and even out skin tone. Licorice’s sweet flavor also makes it a natural sweetener. Because excessive licorice can raise blood pressure (due to glycyrrhizin), moderate consumption is advised.
