What it is
This extract comes from Laminaria ochroleuca, a brown seaweed sometimes called golden kelp. It supplies polysaccharides and other marine-derived compounds and is used as an antioxidant and skin-conditioning agent. In sunscreens and other leave-on products it is included to support a soothed, conditioned feel.
Safety & warnings
Marine algae extracts like this are generally well tolerated in cosmetics and used at low levels. As with any botanical or marine extract, there is a small potential for sensitization in predisposed individuals. It is not a known fragrance allergen and is not an oil, so comedogenicity is not a typical concern.
Origin & sourcing
A natural marine botanical extract derived from the brown alga Laminaria ochroleuca.
