Undaria Pinnatifida (Algae) Extract

Undaria pinnatifida, also known as brown algae, is a type of seaweed that is also edible. As with most seaweeds, it is a rich source of nutrients, and these benefit skin when applied topically.

Among the benefits from applying brown algae to skin are antioxidant properties from its polyphenols, hydration from its polysaccharides, and soothing effects, thanks to a compound known as fucoidan.

Among the benefits from applying brown algae to skin are antioxidant properties from its polyphenols, hydration from its polysaccharides, and soothing effects, thanks to a compound known as fucoidan. In vitro (test tube) research has shown this type of algae plays a disruptive role in the pathway melanin (skin pigment) takes to make it to the skin’s surface. In theory, topical use may help keep discolorations at bay. Some research indicates brown algae has more antioxidants than red or green algae, but topically, all of them can thwart the cascade of damage common airborne pollutants can trigger on skin.
