The ocean bioflora is rich in plants producing molecules essential for their survival that can be useful to protect our skin.
Seaweeds are an amazing source of natural molecules for both nutrition and topical use. They are rich sources of minerals (including the essential micronutrient iodine), bioactive polysaccharides, carotenoids and even proteins, along with a small content of healthy lipids. They have been described as ‘an ideal food’.
Seaweeds are rich in phenols derivatives and polysaccharides with protecting activity (Ref 1, 2) For example, marine polyphloroglucinols, found in brown seaweed, are phenols derivatives with powerful antioxidant properties and significant activity against the damaging free radicals (Ref 3). Brown seaweeds also contain a slippery compound called fucoidan that assists with protection from marine pathogens. Fucoidan is a fucose-rich polysaccharide with anti -viral, immune modulating and matrix metalloprotease inhibiting properties (Ref 4).
