In cosmetics, algae act as thickening agents, water-binding agents, and antioxidants. Some algae are also potential skin sensitiser. For example, the phycocyanin present in blue-green algae has been suspected of sensitisation on the basis of patch tests. Other forms of algae, such as Irish moss and carrageenan, contain proteins, vitamin A, sugar, starch, vitamin B1, iron, sodium, phosphorus, magnesium, copper, and calcium. Most of these are beneficial for skin, as emollients, soothing agents, or antioxidants. New research shows forms of brown algae show promise for improving the appearance of ageing skin. As a plant ingredient, all types of algae are prone to breaking down with routine exposure to air and light. Because of this, avoid anti-ageing products with algae that are packaged in jars.
