PATENTED Earth Marine CellTech Complex®

THE SCIENCE BEHIND EVERY TRANSFORMATION

From the depths of the ocean comes the resilience that defines our approach to skincare. On the wild Atlantic coast of Brittany, our marine biotech experts developed Earth Marine CellTech Complex® – a clean, potent innovation powered by algae, plankton, and a protective Marine ExoPolySaccharides.

These ExoPolySaccharides act like a molecular armor, shielding skin cells from oxidative stress, strengthening the barrier, and maintaining osmotic balance. Combined with mineral-rich deep-sea elements and advanced hydration factors, it creates a dynamic defense and renewal system. The result: resilient, balanced, and visibly revitalized skin – every day.

DEFINITION

Earth Marine CellTech Complex® (EMCC®) is our patented marine biotech innovation that activates the skin’s innate processes through the principle of osmotic balance. It strengthens the barrier, protects cells against environmental and internal stress, and supports the skin’s natural rhythm of regeneration and resilience.
ORIGINS

For billions of years, the ocean has been home to the most adaptive lifeforms on Earth. Microalgae and marine plants have survived its harshest conditions – shifting tides, intense UV radiation, temperature extremes, and oxidative stress – by evolving sophisticated defense systems. Rich in minerals, naturally aligned with the skin’s pH, and exceptionally bioavailable, these marine resources mirror and reinforce the skin’s own biological functions.

Our scientists have captured this natural resilience and transformed it into Earth Marine CellTech Complex®: a fusion of marine-derived actives, mineral elements, and advanced hydration factors. Designed as a chrono-adaptive system, EMCC® works in harmony with the skin’s rhythms – strengthening, hydrating, and revitalizing while fostering lasting vitality and balance.
MARINE BIOTECHNOLOGY

Marine biotechnology is the science of cultivating rare ocean actives, such as plankton, algae and microalgae, in controlled environments to ensure maximum efficacy and purity while protecting our oceans.

Rather than harvesting from fragile ecosystems, we recreate pristine ocean conditions in state-of-the-art bioreactors on the French Atlantic coast in Brittany, producing actives that are uncontaminated, traceable and clinically effective. This process enhances bioavailability, guarantees reproducibility and preserves marine biodiversity, enabling us to harness the ocean's most powerful actives while protecting its ecosystems.

Unlike stem-cell inspired approaches that attempt to 'train' the skin, EMCC® harnesses the adaptive intelligence of marine microalgae and minerals to support natural processes already coded within the skin. Clinically proven to boost renewal, restore balance, and protect against daily stressors, it adapts to the skin’s needs troughout of the day and night.
