Proper care brings beauty, youth, and hydration. The Biotherm logo illustrates the relationship between the company’s products and improved skin. The emblem emphasizes the rich experience and proven effectiveness of cosmetics.
Biotherm’s history began in the late 1940s at thermal springs in the French Pyrenees. Biologist Jos Jullien identified thermal plankton while working in Molitg-les-Bains with Georges Marissal, isolating a microorganism rich in amino acids and minerals.
Jeannine Marissal expanded the research, studied its effect on skin, and patented its cosmetic use. In 1952, she founded Biotherm with Adrien Barthélemy. From the start, the brand distributed through pharmacies, with initial products including Biotherm Cure, La Crème Triple-Usage, and Biomains.
By 1955, The New York Times reported on the brand’s approach. In 1957, La Crème Hydrothermale expanded the line. During the 1960s, Biotherm developed formulas for different skin types and introduced sunscreen in 1967, aligning with the growing spa culture.
In 1970, L’Oréal acquired Biotherm, integrating it into its portfolio to compete with Lancôme and Clarins. In 1974, a seven-story headquarters and production facility opened in Monaco, with Grace Kelly in attendance.
In 1985, Biotherm introduced Biotherm Homme, among the first structured men’s skincare lines, including aftershave and anti-aging products. In 1987, the Biologics range segmented women’s skincare by age, strengthening its presence in Japan.
In 1994, a biotech center in France isolated Life Plankton through fermentation after years of research, laying the foundation for further product development.
Meaning and History
A brand’s logo is its sign because its name is central to it. It demonstrates the company’s importance and informs buyers. Throughout its history, the company has used a single mark.
The logo has two equal parts: text and a graphic element. The word “Biotherm” is original, which makes the logo unique. It connects two letters: “H” and “E.” The designers made them a single element that sets the logo apart.
What is Biotherm?
Biotherm is a French cosmetics company that offers skincare products. It was founded in 1952 after officially obtaining the intellectual property rights to the discovery of thermal plankton in mineral water near the Pyrenees. Biologist Dr. Jos Jullien founded it and named it after the thermal source (therm) and organic life (bio). Since 1970, L’Oréal has owned the brand.
A wide, wavy black line runs along the bottom. It symbolizes thermal water, the main source of the branded cosmetics’ healing properties. The strip does not go beyond the upper word and breaks off at its edges. This creates sharp corners that point up and down.
Font and Colors
The word is set in a smooth, narrow, sans-serif typeface. The letters are elongated and angular, except for the streamlined “O.” The “HE” signs connect into a single unit. The emblem’s palette is monochrome: black elements on a white background.
