What is Biotherm known about?

Biotherm is a French skincare brand with its origins in the Pyrenees. In the forties and fifties, the French doctor Jos Jullien, originally from Joyeuse in the Ardèche, noticed a special substance on the surface of the thermal springs of Molitg-les-Bains. That substance consists of thermal plankton.

From spring water to skincare

Together with Jeanine Marissal, Jullien researched how the thermal plankton could be incorporated into a cosmetic formula. That work led to Biotherm in 1952, under the direction of Adrien Barthélémy, the owner of the springs of Molitg-les-Bains. That same year the brand released three skincare items: La Crème Triple-Usage, Biotherm Cure and the hand cream Biomains.

Growth and expansion

In the sixties Biotherm developed skincare for specific needs, including the brand's first sunscreen. In 1970 Biotherm was acquired by L'Oréal. The brand also has a skincare line for men, for which actor David Corenswet became ambassador in 2024, succeeding Nicholas Hoult.

The name

The name Biotherm refers to those origins: 'therm' stands for the thermal plankton in the brand's skincare, and 'bio' for the profession of the founder, who was a biologist.
