Biotherm was founded in 1952 by Jeannine Marissal in thermal springs in Southern France. Thanks to the pure water which contain active essentials, the way to produce natural care products was short. The secret ingredient in Biotherm's products is the thermal plankton that is found in the water and was found to have curing abilities. Ever since, Biotherm has become one of the most known companies to produce natural thermal water based products.
