Traditional Use
Fucus vesiciosus (bladderwrack) has been used in traditional European medicine and skincare for centuries as a source of iodine and minerals. The plant was valued in coastal communities for skin nourishment and was later processed into hydrolyzed form in the 20th century to improve bioavailability and texture in cosmetics.
