Fish Antifreeze is new skin anti-ageing secret


An anti-aging compound based on the naturally occurring ‘antifreeze’ glycoproteins found in Antarctic fish may be the next big thing in anti-ageing skin care.

arctic fishThe fish –antifreeze’ was first discovered in the late 1960s by Professor Arthur DeVries, who established that the resistance to freezing temperatures in Antarctic fish was due to blood serum glycoproteins that protected the fish cells against the harsh and freezing environment.

Professor DeVries findings, published in the Proceedings of the National Academy of Sciences, were the first to search the genome of  Antarctic fish for clues to their astounding hardiness. DeVries discovered some Antarctic fish manufacture their own “antifreeze proteins.”

Half a century later, Canadian-based biochemical company Sirona Biochem have now developed a synthetic copy of these fish antifreeze compounds that is suitable for use in skincare products.

Published Australian research carried out at The University of Sydney found that Antifreeze glycoproteins (AFGPs) constitute the major fraction of protein specifically found in the blood serum of Antarctic notothenioids and Arctic cod.

There are eight families of notothenioid fish, and five of them inhabit the Southern Ocean, the sea that encircles the Antarctic continent. These fish can withstand temperatures that would turn most fish to ice. Their ability to live in the cold and oxygen-rich extremes is so extraordinary that they make up more than 90 percent of the fish biomass of the Southern Ocean.

The ability of these compounds to modify the rate and shape of crystal growth and protect cellular membranes mean that they have potential for use in skincare for the preservation and hypothermal storage of skin cells and tissues. Skincare giant L’Oreal has already singled out the new ingredient for use in their future anti-ageing skincare products.
