The Body Shop® difference: Our wild-harvested seaweed comes from our fantastic Community Trade partner in Ireland, the Roaring Water Bay Seaweed Cooperative. Bladderwack is a type of brown seaweed that grows on the northern Atlantic and Baltic coasts of Europe. It has the largest trace mineral content of any known single source of seaweed and contains high levels of iodine, antioxidants and vitamin B. Because it is grown without chemicals or fertilizers, it is safe to use on any skin type or at any age to help control shine.
