Furcellaria lumbricalis is a red-coloured algae that grows on rocks off the northern coast of Scandinavia. Also known as Carrageen, Agar-agar or ""Crab Bed, this hardy algae can survive low tides and dry conditions thanks to its superior rehydration capabilities. Red algae has hygroscopic properties, which means it easily attracts and retains water, making it an excellent ingredient to help invigorate, soften and revitalise the skin.

Furcellaria lumbricalis contains a structural polysaccharide called furcelleran, which helps revitalise dehydrated skin thanks to its hygroscopic and gelling properties.
