The company has been operating since 1988 near Bréhat Archipelago on the Northern coast of Brittany (France). Its expertise is world recognized.

BiotechMarine offers a range of 60 active ingredients, for use in cosmetic and haircare products, marketed by the sales network of SEPPIC.
BiotechMarine focuses its efforts on innovation, safety, effectiveness, sustainable development and the preservation of biodiversity.

BiotechMarine combines the reactivity and dynamism of a medium-size company with the robustness of SEPPIC, an international group.


Devoted to protecting biodiversity, BiotechMarine selects specific marine plants and algae from remarkable sites.

The Bréhat Archipelago (in Northern Brittany, France) is home to an exceptional marine flora — over 800 species of algae and hundreds of species of marine plants.

It is one of the world's most remarkable sites in terms of algal diversity, favored by:

  • Water purity and quality.
  • The confluence of a warm and nutritious current, the Gulf Stream from the Mexico Gulf, and a cold and pure current, the North Stream from the Northern Sea.
  • An "underwater Amazonia".
  • An ecosystem favourable to the development of unique secondary metabolites by the algae & marine plants due to the environmental stress.
