Fucus Vesiculosus (bladderwrack seaweed) extract is a marine botanical rich in polysaccharides, polyphenols, and minerals used in skincare for its moisturizing, antioxidant, and skin-conditioning properties. It may help improve skin hydration and elasticity, though robust clinical evidence is limited.
