"Licorice root extract contains the antioxidant glabridin and licochalcone A, which both have powerful anti-ageing and skin-soothing properties," said Dr. Nussbaum. "This ingredient can help those with sun-damaged or red, irritated skin." This is because it helps brighten skin by blocking the enzymes responsible for triggering skin darkening from UV radiation. The Coola Moon Silk Moisture Recharging Mask ($48) allows you to experience this brightening ingredient in just a 10-20 minute treatment.
