Biotherm Life Plankton Elixir Fundamental Regenerating Treatment 30ml is a celebrated regenerating treatment serum from French marine-active skincare house Biotherm.

About Biotherm
Biotherm is the French skin-care house owned by L'Oréal under the Luxury Products division, acquired by L'Oréal in 1970. The brand's heritage is rooted in thermal mineral water: in the early 20th century, French doctor Jos Jullien discovered mineral thermal spring waters under the Pyrenees mountains in southern France containing the unique Life Plankton microorganism — Biotherm's signature active. The brand's products use this proprietary Life Plankton extract at the heart of their formulas.
