Algae

Marine algae are chlorophyll-containing organisms, ranging from simple single cell formations to more complex multi-cell forms, such as seaweed. Seaweed is a natural thickening agent commonly found in cosmetics. It is also used for its water binding and antioxidant attributes. Blue-green algae may cause skin irritation.
