Algae Extract has been used in alternative cosmetics for skin related diseases since ancient times. Currently, algae extract has been widely used in skin care products because it is rich in bioactive compounds. Algae extract is formed from four main seaweed classes: red algae, brown algae, blue-green algae, and green algae. Each class contains molecules that promote skin benefits such as: omega 3 fatty acids, amino acids, and vitamins A, B, C, and E. 1
