Fucus Vesiculosus Extract description

_Fucus vesiculosus_ extract, also known as bladderwrack, is a type of brown algae (seaweed) that is edible. Its nutrient profile benefits the body when consumed, but it can also benefit skin when applied topically. One of the more notable topical benefits is how the treasure trove of antioxidants in brown algae can help defend skin’s surface from daily exposure to airborne pollutants. The antioxidants help neutralise these substances before they cause ongoing harm. Fucus vesiculosus has an unusually high concentration of minerals, including sodium and potassium, and the full suite of essential amino acids, which can help facilitate the movement of water through skin’s uppermost layers.
