Chronobiology

CHANGING SKIN NEEDS.
DISTINCT DAY & NIGHT CARE.

Your skin’s needs change throughout its 24-hour cycle. Molecular clocks within its cells regulate biological processes, while barrier function and moisture loss vary between day and night.

These changes influence how your skin retains hydration, responds to daily exposure and renews itself.

GEZEITEN translates this science into distinct day and night formulations. Comprehensive care in fewer products, developed around your skin’s rhythm.

THE RIGHT ACTIVES. AT THE RIGHT TIME.

THE RIGHT ACTIVES. AT THE RIGHT TIME.

Chronobiology guides both which actives we select and when they are used. Our distinct day and night formulations account for changes in skin function and permeability - designed to optimise active ingredient delivery and strengthen the skin’s own biological processes.

By day, this means reinforcing protection and moisture retention. By night, stimulating renewal and replenishing the barrier. Targeted care for each phase, for hydrated, smoother and more resilient skin.

DAY · PROTECTION & PREVENTION

Pollution, blue light exposure and daily stress can accelerate collagen degradation and trigger excess pigmentation - leaving skin less firm, uneven and visibly fatigued.

Our day formulations counter oxidative stress, protect collagen from degradation and strengthen the skin barrier. Targeted actives regulate excess melanin production to prevent and reduce hyperpigmentation, while retaining moisture and smoothing fine lines.

For hydrated, firmer and more even-looking skin.

NIGHT · REGENERATION & RENEWAL

Daily stress, disruption to your skin’s natural rhythm and poor sleep can leave skin dry, dull and visibly tired.

Our night formulations stimulate cellular renewal, replenish moisture and restore the protective barrier. Targeted senolytic actives in our night serum address dysfunctional, senescent cells, while complementary actives stimulate collagen production, improve skin structure and reduce visible wrinkles, uneven texture and signs of fatigue - according to your skin’s specific needs.

For firmer, smoother and more rested-looking skin.

FROM RESEARCH TO FORMULATION

Developed through years of research in Germany and in collaboration with Professor Dr. Gregor Eichele, a leading researcher in biological rhythms, Emeritus Director at the Max Planck Institute for Multidisciplinary Sciences and former Harvard Medical School faculty member, GEZEITEN translates chronobiology into daily skincare.

The skin’s changing biological needs guide our selection of actives and the development of complementary day and night formulas.

Daytime protection. Nighttime regeneration.

SCIENTIFIC TEAM

  • FOUNDER & HEAD OF INNOVATION

    Michaela translates biological intelligence into skincare that works in real life. By combining scientific insight with a deep understanding of modern skin challenges, she develops formulations designed to support how skin actually functions — not just how it appears. Working closely with leading scientists, she...
  • CHRONOBIOLOGY & EPIGENETICS

    A global authority on biological rhythms, Prof. Dr. Eichele provides the scientific foundation of GEZEITEN. His research enables formulations that align with the skin’s natural 24-hour cycle — supporting protection during the day and optimizing regeneration at night. This approach allows skincare to work with...
  • MARINE BIOTECHNOLOGY

    Through our partnership with CODIF and their 40+ patents, under the scientific direction of Prof. Dr. Pierre-Yves Morvan, we harness the adaptive intelligence of marine ecosystems. Instead of extracting from nature, these actives are sustainably cultivated — ensuring maximum purity, stability, and consistent performance. They...
  • FORMULATION ARCHITECTURE

    Developed in German laboratories, each formula is designed as an interconnected system — not a collection of individual ingredients. Multiple actives are precisely combined to work synergistically, enhancing each other’s performance and improving how effectively the skin can respond. This replaces complex layering with a...
  • DERMATOLOGICAL AUTHORITY

    Developed alongside dermatologists and experienced skin experts, each formula is designed to address the underlying causes of imbalance — not just visible symptoms. Clinically grounded and sensorially refined, GEZEITEN combines performance with an elevated daily ritual.
