A powdered extract from the red seaweed Grateloupia livida, rich in polysaccharides (natural sugars) and minerals that support skin hydration.
How it works
The polysaccharides in the powder form a thin, water-loving film on the skin's surface, which helps attract and retain moisture. This film also has mild soothing properties, potentially reducing redness or irritation.
