Patented Earth Marine CellTech Complex®

THE BIOADAPTIVE CORE

At the core of every GEZEITEN formula lies our Earth Marine CellTech Complex® (EMCC®), a bioadaptive system designed to strengthen how your skin functions.

Marine organisms thrive in extreme, constantly changing environments. Through advanced marine biotechnology, based on controlled cultivation and precise extraction, we harness this adaptive intelligence and translate it into skincare.

Each active is carefully selected and formulated to work as part of a functional system, not as isolated actives, designed to strengthen the skin barrier and support long-term skin function.

Developed in collaboration with marine biotechnology experts

EMCC® has been developed over years in close collaboration with CODIF in Brittany, France, a leading marine biotechnology laboratory with access to one of the most diverse marine ecosystems in the world. This unique region, shaped by extreme tides and constant environmental change, is home to highly adaptive marine organisms that have evolved over billions of years.

Drawing from this resilience, we develop advanced marine actives, from bioavailable marine minerals to barrier-strengthening ferments and hydration-supporting biotechnological sugars.

Each formula is the result of continuous research, testing, and refinement, ensuring stability, performance, and optimal compatibility with the skin.
Why Marine Biotechnology

Marine biotechnology uses marine organisms, such as algae and microorganisms, cultivated in controlled environments to develop high-performance active ingredients for skincare.

Instead of harvesting directly from the ocean, these actives are obtained through controlled cultivation and precise extraction processes, ensuring stability, purity, and optimal compatibility with the skin.

This approach not only preserves natural marine ecosystems, but also allows for consistent quality and highly targeted, bioadaptive ingredients.
