Fucoidan’s skin brightening, protection and repair


n Claire Smoorenburg, Dr Helen Fitton – Marinova, Australia


Fucoidans are unique fucose-rich polysaccharides naturally found in the cell walls of brown seaweed. They are highly bioactive compounds that play a pivotal role in protecting seaweed from water-borne pathogens and damage caused by ultraviolet light (UV). Extensive research has shown that fucoidan extracts can similarly impart protective effects on the skin and have diverse benefits in dermatological applications. Fucoidans are highly branched, complex


polysaccharides of varying size, typically with a high molecular weight. Fucoidans are characterised chemically using validated assays that quantify the sulfation, acetylation, molecular weight and the content of sugars in the carbohydrate ‘backbone’. Fucoidans differ in chemical structure and bioactivity depending upon the species of seaweed from which they are derived, and the method by which they are extracted. Australian biotechnology company, Marinova, specialises in the
