Manufacturing

At this time, LSI does not own its proper Manufacturing facilities but relies on three contract-manufacturing partners.
This is a deliberate choice, in order to dedicate the best of our investments to our core business, R&D and marketing.
Meanwhile our manufacturing partners were carefully selected in order to ensure that physicians’ and customers’ needs are met using high service standards.

We currently possess three manufacturing sites. The two cosmeceuticals sites are located one in France, in the Rhône-Alpes region and the second one in Switzerland, in the Wallis canton.

In Switzerland and in France, perfection is a second nature.
Our partners’ permanent concern is maintaining constant quality to offer the best products with highest standards.
Both are implementing for a long time quality control processes to ensure the excellence of our products, under our strict and permanent supervision. Both are in compliance with the ISO 22716 standards and have certification from SWISSMEDIC, the Swiss medical agency.

As regards to nutraceuticals, they are elaborated in Switzerland by a GMP- Certified company. Further to applying international GMP standards, Rocnarf Labs. is proud to be certified ISO 9001-2008 by SGS.
