What it is
An extract from the red algae species Ceramium kondoi, rich in polysaccharides and minerals that support skin hydration.
How it works
The polysaccharides in the extract form a thin film on the skin's surface, helping to reduce water loss (transepidermal water loss, or TEWL) while also providing a light, soothing sensation. It may also have mild antioxidant properties.
