Innovation, Efficiency and Security


In medicine, and more especially in Dermatology, there is still a large amount of unmet needs, that is, disorders for which there is no response
satisfactory for the dermatologist and his patients.
Our goal is to explore these unmet needs in a close relationship
with doctors, and the development of innovative products tailored to their needs.
Most LSI products are patented and have the advantage of a strong
protection in terms of intellectual property.


Any product launched by LSI is backed by serious and published clinical studies, able to demonstrate their effectiveness and safety.
For us, a new product should not only be innovative, it should also bring an additional benefit for the patient, compared to existing products.


“Primum non nocere” is an important motto in medicine.
In addition to being active, a dermatological product must be completely safe for the patient. Most treatments have side effects that make its dubious benefit, especially over long periods of time.
We at LSI firmly believe that an adequate dermatological treatment must be safe.

Our Faith is in Vegetal Active Ingredients

We are certain at LSI that nature, especially plants, can bring us resources permitting to treat almost any kind of skin disorder.
The matter is not translating folk medicine to Dermatology, but our commitment is rather in identifying the right active ingredient from the right plant, and making sure that we are able to reproduce the same quality batch after batch.
We never use in our formulations any ingredient from animal origin, and try to avoid as far as possible the use of synthetic components.

Swiss Quality:

“MADE IN SWITZERLAND OR MADE IN FRANCE” is more than a simple label of origin.
It is a guarantee for customers who are buying a product of quality and reliability.
All LSI products are produced in GMP plants equipped with the latest technology.
These plants are located in Schötz (Switzerland) and Château-Gaillard (France) while our logistics facilities are located in St-Maurice (Valais).

Global vision:

Along years, we developed our distribution network on six continents, all over the world.
This is a matter of pride for LSI, having pharmaceutical partners in more than 70 countries, where our products are professionally promoted to physicians, and sold exclusively through pharmaceutical channels. We intend to have the best partners everywhere, and one word has a very special meaning for us: ethics.
