In 1952, Jeanine Marissal, a young visionary biochemist discovers the remarkable healing properties of thermal plankton springing from its exceptional biological affinity with our skin. She believed in enhancing skin life natural processes and hence patented the use of thermal plankton in skincare products. After years of research, thanks to a unique and natural fermentation process developed by our bio-scientists, called Fermogénèse™, Life Plankton was extracted, the most active extract for skin: a powerful natural activator of skin life functions. Water has been at the heart of Biotherm’s DNA since the creation of the brand. In 2012 the Biotherm Water Lovers program was created to work towards a better future for our oceans.​
