The glabridin extracted from a licorice root gives us more than just that sweet-flavored candy. It is also an antioxidant that brightens and calms the skin. Licorice extract is commonly found in creams and serums that reduce redness and calm skin conditions such as rosacea and eczema. Licorice root extract can also be found in shampoos that work to reduce oiliness and soothe a dry scalp.
