In the early 20th century, the French doctor Jos Jullien discovered mineral thermal spring waters under Pyrenees mountain in the southern part of France which contained thermal plankton, supposedly a key to healthy skin and a potent skin rejuvenator.^[1][2] In 1952, intellectual property rights were acquired and he used it in skin care products. Thus, therm in Biotherm comes from thermal plankton, an ingredient found in all Biotherm products.^{[citation needed]} Bio comes from the profession of the founder biologist.

In the years 1940-50, Dr. Jos Jullien,^[3] from Joyeuse in Ardeche (France), noticed the presence of a particular substance on the surface of the thermal waters of Molitg-les-Bains. This substance is composed of thermal plankton. With Jeanine Marissal, he worked on the potentials of this substance that could be integrated towards creating a cosmetic formula. Biotherm was born from this work in 1952,^[4][5] under the leadership of Adrien Barthélémy, owner of the Molitg-les-Bains springs. In 1952, Biotherm launched 3 products: La Crème Triple-Usage, Biotherm Cure and Biomains. Biomains, a hand moisturizing cream, is still on the market today.^[6]

During the 1960s the brand developed several targeted skincare solutions to address specific needs, including its first sun cream and its first "slimming cream".^{[citation needed]} In 1968, Biotherm introduces Bio-Buste Suractive on the market, its first "breast firming cream".^{[citation needed]}

Biotherm was acquired by L'Oréal in 1970.

In 2014, Leighton Meester was appointed as the new global spokesperson for the skin care brand Biotherm.^[7]

In 2016 David Fridlevski was appointed brand president.^{[citation needed]}
