What it is
An extract from the brown seaweed Pylaiella littoralis, harvested from marine environments. It contains natural compounds like polyphenols and polysaccharides that are thought to benefit the skin.
How it works
The extract's polyphenols act as antioxidants, neutralizing free radicals that can damage skin cells. Its polysaccharides may form a light film on the skin, helping to retain moisture and calm irritation. It is typically used in low concentrations as a supporting ingredient in formulations.
Pros

Helps protect skin from free radical damage without causing irritation, making it suitable for sensitive skin types.
Soothing properties

Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are not fully proven.
