Located on the north coast of Brittany (France), near the Bréhat archipelago, BiotechMarine is our production site dedicated to wesource™ cosmetic active ingredients derived from marine biotechnologies (dedifferentiated marine plant cells and macroalgae cells) and seaweed or marine plant extraction. These marine active ingredients are intended for skin and hair care products.

BiotechMarine selects marine plants and particular algae on remarkable sites, with an approach that respects biodiversity. The Bréhat archipelago is home to an exceptional marine flora, with over 800 species of algae and hundreds of species of marine plants. A true "Underwater Amazon," it is one of the most remarkable sites in the world due to its variety of algae favored by the interplay of several factors:

  • The purity and quality of its waters
  • The confluence of a warm, nutritious current, the Gulf Stream from the Gulf of Mexico, and a cold, pure current, the North Stream from the North Sea
  • An ecosystem conducive to the development of unique secondary metabolites by algae and marine plants related to environmental stresses.

The site has four manufacturing units. It also houses innovation laboratories dedicated to marine active ingredients.

It is ISO 9001:2015 and RSPO certified and is being EFfCI certified. 100% of the ingredients are Halal certified and 100% of the ingredients whose production uses palm oil derivatives are Mass Balance certified (follow our RSPO progress).
