The past

“Caring for people’s hair is like caressing their soul” – these words once uttered by the founder of our brand, Marcel Contier, perfectly sum up our corporate philosophy. More than seven decades ago, the French biochemist revolutionised the world of hair care with an approach that was as simple as it was ingenious: combining “bios” (life) with “esthétique” (aesthetics). 


Inspired by a holistic look at all aspects of life, we develop product lines that view the body not as a sum of individual parts but as a single entity. We focus on body care in its entirety – from head to toe.

Family company

Marcel Contier founded La Biosthétique, and Siegfried Weiser and his family worked together with Contier to transform it into a successful brand. The two families worked side by side for many decades before the Weiser family ultimately took over the entire company.

Black Forest

Our calmness and purity come straight from the nature of the Black Forest, where we manufacture our products in line with the highest quality standards. When doing so, we use nothing but high-quality ingredients and rely on sustainable production processes. The nature of the Black Forest is not only our home and our source of inspiration but also the location of our research and production facilities. Working in harmony with nature is a matter close to our heart.
