Laboratoire Mergens

For your well-being

Using nature and technical skill, the Swiss company Laboratoire Mergens is the result of a perfect symbiosis of fundamental research and innovation, to offer effective, innovative and patented niche products, in the service of beauty and well-being.

It all starts back in 1993 when Serge Leuthold, an avant-garde scientist developed a passion for fundamental research and particularly, the extraction of active ingredients from plant sources (plants, aromatics…). He realised that nature provides unexploited treasures to treat, embellish and to improve both the outer and inner well-being.

He observed that with the use of a quality dietary supplement, improved physical and intellectual performance can be achieved; these are the first steps towards the science of nutrition.

In 2002, the company acquired several pharmaceutical patents in expanding and diversified fields: skin pigmentation, skin injuries and a few years later tinnitus. They are continuously re-evaluated in order to develop original cosmetic applications and to launch new niche market products.

Today Laboratoire develops its activities in various fields such as food supplements, derma cosmetics (with its Nerola® product family) and medical devices.

The products are distributed in more than 20 countries on three continents: Europe, Africa and Asia.

As its beauty philosophy, Laboratoire Mergens has developed a global concept:
“Deep Beauty”, which reflects the idea that beauty, born from and felt within, is also reflected on the outside.


The Laboratoire Mergens R&D team develops unique and innovative formulas, completely in keeping with the needs of the market.
With this in mind, it selects with care the ingredients for each product: the active ingredients for their effectiveness and the excipients for their texture, their aroma and their taste.


Laboratoire Mergens draws its strength from its double expertise:

– development and commercialisation of its own brand products 
The company offers innovative, high performance and patented products in expanding and diversified fields: skin pigmentation, skin injuries, tinnitus…

– formulation and manufacture of products on behalf of third parties
For many years now, several major French retailers (such as Système U or Carrefour) have entrusted Laboratoire Mergens to manage the subcontracting of their products.


Laboratoire Mergens puts in place rigorous selection methods for both its subcontractors and its suppliers defined by European quality norms (ISO, GMP, HACCP…).
The company itself has had ISO 9001 certification since 2012. This certification is proof of its deep commitment to quality towards its clients.


The Scientific Committee consists of experts in the fields of health and science (pharmacy, medicine, biology, biotechnology…), who are charged with defining the scientific policy of Laboratoire Mergens. They are involved in product development and contribute to the creation of technical information to be released by the company.
