Key Ingredients
Clinically proven. Precisely dosed. Perfectly Timed.

Earth Marine CellTech Complex®

Our patented marine complex supports the skin’s ability to adapt to environmental stress. Concentrated marine minerals and bioactives help strengthen the barrier, improve resilience, and support long-lasting hydration from within for balanced, healthier-looking skin.
Green Microalgae Extract (Biotech Chlorella)

Rich in antioxidants and up to 70% plant proteins, this green microalga protects against free radical damage, smooths wrinkles, and stimulates cellular regeneration through its unique Chlorella Growth Factor (CGF). With its wealth of proteins, peptides, and amino acids, it acts as a true skin energizer, boosting resilience against stress and environmental aggressors while supporting detoxifying processes for a youthful, healthy appearance.
Marine Moisture Sugars (Biotech Saccharide Isomerate)

This unique marine-derived sugar complex works like a moisture magnet, binding to the skin for up to 72 hours of continuous hydration. It not only locks in water but also strengthens the skin barrier, ensuring long-lasting comfort and a plump, radiant look.
Rainbow Seaweed Extract (Cystoseira Tamariscifolia)

A rare algae from Brittany’s pristine coast, celebrated for its iridescent tones and its remarkable “melanobrake” effect. It slows down excessive melanin production to visibly reduce dark spots and balance uneven pigmentation. At the same time, it restores luminosity and shields the skin from oxidative stress. Clinical studies confirm a brighter, more even, and radiant complexion.
Cranberry Stem Cell Extract (Biotech Vaccinium Vitis-Idaea Fruit)

Derived from resilient Arctic cranberries, this advanced stem cell extract is packed with polyphenols and anthocyanins that deliver strong antioxidant defense. Clinically shown to protect against blue light–induced oxidative stress, it helps safeguard collagen, prevent premature cell damage, and maintain youthful vitality. Skin feels more resilient, smoother, and visibly radiant, even under daily digital and environmental stress.
Palmitoyl Tripeptide-38

A next-generation peptide that acts directly within the skin’s matrix, the structural framework responsible for firmness and elasticity. It boosts collagen and hyaluronic acid, supporting the rebuilding of the skin’s support system from within. The result is visibly smoother skin with reduced wrinkle depth and a plumper, more youthful appearance.
Oat Kernel Extract & Lactobacillus Ferment

This unique combination of oat extract and probiotic ferment provides soothing care for sensitive and stressed skin. It helps rebalance the skin’s microbiome, reducing redness and irritation while strengthening barrier function. The result is enhanced comfort, resilience, and long-term skin health.
Niacinamide (Vitamin B3)

A multitasking vitamin that strengthens the skin barrier and improves overall skin clarity. It regulates sebum production, minimizes the appearance of pores and impurities, and calms sensitivity. Niacinamide also supports natural ceramide and collagen synthesis, brightens uneven tone, and enhances elasticity and radiance - for a smoother, more balanced, and healthier-looking complexion.
Multi-Molecular Hyaluronic Acid

Combining different molecular sizes of hyaluronic acid, this complex hydrates at multiple skin levels, plumps fine lines, and enhances elasticity.
Squalane

A plant-derived, skin-identical lipid that mimics the skin’s natural sebum. It restores the skin’s moisture balance, improves elasticity, and reinforces the barrier. Its lightweight, non-comedogenic texture leaves the skin smooth and soft without any greasy residue.
Lactic Acid

A naturally occurring skin-identical component used to regulate and stabilise the skin’s pH value. By supporting the skin’s natural acidic environment, it strengthens barrier function, improves hydration efficiency and enhances overall skin comfort.
