Plankton Extract



Plankton Extract description

A marine species known as Thalasso plankton and derived from various algae, seaweed, or marine skeletons. There is no research showing plankton extract has any benefit for skin but, like most forms of algae, it can have moisture-binding properties. Although that’s good, keep in mind plankton ism’t a miracle (not even a minor one) or a must-have ingredient for skin.
