Mécanisme
Action moléculaire
Fucoidan stimulates fibroblast proliferation and the synthesis of type I collagen. The alginates form a film-forming hydrating layer. The minerals (Mg, Ca, K) are cofactors of cellular metabolism enzymes — they support regeneration.
Origine et tradition
Du palais aux laboratoires
Dasima seaweed has been in Korean cuisine since prehistoric times — the base of the traditional broth (yuksu). In cosmetics, its use became widespread in the 20th century, but Ulleungdo fisherwomen were already using it as a compress on sun irritations.
