What it is
This ingredient is a combination extract drawn from multiple marine algae species, including red, brown, and green seaweeds. Seaweed extracts are valued in cosmetics for their naturally occurring polysaccharides and minerals, which can help condition the skin and support a soft, smooth surface feel. In a sunscreen it functions as a supporting botanical rather than as a UV filter.
Safety & warnings
Blended seaweed extracts are generally well tolerated in cosmetic use. They are not recognized as common comedogenic ingredients. As with any botanical blend, individuals with known sensitivities to marine-derived ingredients may wish to take usual care.
Origin & sourcing
The extract is naturally sourced from marine algae, derived from the listed red, brown, and green seaweed species harvested from the sea.
Questions everyone asks
Does this seaweed blend provide sun protection?
No. It is a conditioning botanical and does not act as a UV filter; sun protection comes from the dedicated filters in the formula.
Why are so many seaweeds combined into one ingredient?
Formulators use blended algae extracts to combine the conditioning components of several species into a single botanical ingredient.
