True herbal, earthy and medicinal aroma of Tea Tree Essential Oil, is the highlight of this soap. Tea Tree has long been a favorite in skincare formulations. Charcoal is another ingredient that has taken the cosmetics world by storm. They’ve both been a favorite for MANY years. The rich earthiness of Tea Tree, combined with the oil-removing quality of Charcoal, make this a wonderfully cleansing (yet gentle) bar of soap.
