Chondrus Elatus/Saccharina Angustata/Monostroma Nitidum Thallus Extract

A blended extract of three marine algae, used in cosmetics as a skin-conditioning ingredient.

What it is

This is a combined extract drawn from the thalli of three seaweeds: the red alga Chondrus elatus, the brown alga Saccharina angustata (a kelp), and the green alga Monostroma nitidum. Such marine blends supply mixed polysaccharides and minerals that help bind water and condition the skin. It is used at low levels as a botanical conditioning complex.

Safety & warnings

Used as a topical marine-extract blend for conditioning and is generally well tolerated. Because it is a water-soluble algae extract rather than an oil, it is not associated with comedogenicity.

Origin & sourcing

Natural; obtained from three species of red, brown, and green marine algae harvested chiefly in East Asian coastal waters.
