Algae extracts are of the microalgae Nannochloropsis oculata.

Other forms of seaweed, such as Irish moss and carrageenan, contain proteins, vitamin A, sugar, starch, vitamin B1, iron, sodium, phosphorus, magnesium, copper and calcium. Most of these substances are beneficial to the skin, acting as emollients, soothing agents or antioxidants.
