This recipe, although i haven't tried it yet is a perfect seawater therapy treatment. Very easy to prepare at home too. Always check your local health food store if they have the supply, well usually they do. Seaweed is rich in iodine and protein, which are directly absorbed into the skin helping in the detoxification process. Aloe gel helps regenerate and soothe damaged skin or dry skin. Next to fresh seaweed, the freeze-dried powder is seaweed in its purest form.
