Survival of red microalga cells in the extreme conditions of the ocean tidal zone while subjected to a wide range of harsh conditions, such as overexposure to and constant changes in UV, pH, temperature, hydration and salinity, is attributed to the protective polysaccharide (PS) synthesised in the cells and creating an active shield around them.

In a number of studies the PS has demonstrated a wide range of biological activities, including anti-inflammatory, anti-irritant, anti-oxidant, UV absorbance and bio-lubricant properties, explaining in part its protective effect on the algae cells, as well as protection of the human skin. Over 20 years of research have resulted in an innovative patented growth process.
