Sargassum Vulgare Extract

Sargassum vulgare extract is derived from a species of brown macroalgae (seaweed) commonly found in coastal waters. Like many marine botanicals, it contains polysaccharides, minerals and trace elements that have been used traditionally in skincare formulations.In cosmetic products, this ingredient functions primarily as a skin conditioner, helping to maintain skin's hydration and support its natural barrier function.

Seaweed extracts work through multiple mechanisms. The polysaccharides they contain form a light film on the skin's surface, which helps reduce transepidermal water loss and maintain hydration. Additionally, the mineral profile supports natural skin functions and may have mild antimicrobial properties, though the significance of these effects in skincare remains modest.

Sargassum vulgare extract is typically incorporated into serums, moisturisers and hydrating treatments. Use it as part of your regular skincare routine — consistency matters more than frequency. There are no specific restrictions on combining it with other ingredients, though always introduce new products gradually if you have sensitive skin.

Generally well-tolerated by most skin types. Those with iodine sensitivity should check product formulations, as seaweed-derived ingredients contain naturally occurring iodine.
