BIOTHERM
Biotherm was founded in 1952 in the French Pyrenees, after Dr. Jos Jullien discovered thermal plankton at the Molitg-les-Bains hot springs and biochemist Jeanine Marissal pioneered its use in skincare. Part of L'Oréal since 1970, Biotherm remains rooted in the restorative power of thermal plankton.
