GEZEITEN brings together pioneering marine biotechnology and chrono-adaptive formulation. Every product is designed to work in harmony with the skin’s natural rhythm - supporting protection and vitality by day, and regeneration and repair at night.

Skincare is often designed to fix what already went wrong.
GEZEITEN is designed to keep skin in balance - by working with its rhythm, not against it.
This is how beauty becomes prevention, not just correction.

We reinvented how skincare works: fewer products, deeper logic, maximised skin health. Our clean, microbiome-friendly formulations and transparent science deliver luxurious skincare with real, visible results.

GEZEITEN is designed to support the skin exactly when it needs it, aligned with its natural cellular functions and biological rhythms. Our formulations guide the skin through its daily phases, helping it stay balanced, function optimally, and reach its full potential.

During the day, our products support protection, energy, hydration, and the strengthening of the skin’s natural defense mechanisms.

At night, they enhance renewal, repair, and deeper regeneration — precisely when the skin is biologically most receptive.

Our approach is rooted in prevention and skin longevity: instead of addressing concerns only after they appear, GEZEITEN works with the skin’s rhythm to keep it balanced, resilient, and healthier over time.

Each formula offers multiple synergistic benefits, addressing the skin’s essential needs simultaneously - hydration, protection, firmness, clarity, radiance, and barrier strength - without unnecessary steps or excessive layering.

The result is skin that becomes smoother, stronger, more even in tone, and naturally radiant.

Yes. GEZEITEN is formulated to be compatible with sensitive, reactive and easily irritated skin. We avoid common sensitising or disruptive ingredients and follow a microbiome-friendly formulation philosophy to keep the skin balanced and supported.

Our SERUMS and AMPOULES are suitable for all skin types and can be easily integrated into any routine.

Our two face cream lines offer more tailored support depending on your skin’s needs:
LIQUID SKIN is ideal for sensitive, combination, breakout-prone or younger skin, as well as for anyone looking for lightweight hydration and barrier support.
INTENSIVE ANTI-AGING is ideal for mature, dry or demanding skin, or for those seeking deeper nourishment, firmness and visible anti-aging performance.

If you’re unsure which line is best for you, our expert team is happy to guide you personally at contact@gezeiten.com.

Chronobiology studies the body’s natural rhythms.
The cellular processes of the skin differ significantly between day and night - and GEZEITEN formulations are designed to support these biological needs with precision.

By aligning skincare with these biological cycles, we create a more intelligent, preventative approach: strengthening the skin when it is defending itself, and enhancing renewal when it is naturally repairing.

This rhythm-based method is our version of gentle, science-driven skin biohacking - working with the skin’s own intelligence to improve resilience, longevity and long-term skin health.

GEZEITEN combines pure natural ingredients with scientifically advanced bioactives - each one selected for its potency, stability and exceptional skin benefits.

Where nature reaches its limits, we enhance it through cutting-edge biotechnology, allowing us to use highly effective, sustainably cultivated ingredients without burdening natural ecosystems.

All actives that can be sourced in Europe are sourced in Europe. Our marine actives, developed with our scientific partners in Brittany, represent the highest level of modern biotechnology:
they are cultivated in controlled environments, sustainably extracted and known for their high bioavailability, meaning the skin can recognise and utilise them exceptionally well.

As pioneers in marine biotechnology, we focus on ingredients that work with the skin, supporting its natural rhythms, enhancing resilience and delivering visible results without irritation.

The result: formulations that are clean, gentle and truly high performance.

Yes. Our commitment goes far beyond avoiding parabens, sulphates or mineral oils.

GEZEITEN formulas exclude unnecessary fragrances, allergens and irritants, guided by a continuously updated ingredient blacklist that reflects the latest scientific understanding of skin health and sensitivity.

STABILISATION SYSTEMS Instead of conventional synthetic preservatives, we use modern, naturally derived alternatives. Phenoxyethanol has been completely removed from all GEZEITEN products. For us, true refinement means choosing systems that support skin health, prevention and responsibilit, throughout every stage of the product lifecycle.

FRAGRANCE & ALLERGENS Fragrance blends, even “natural” ones, almost always require alcohol as a carrier. While effective for dispersion, alcohol can dry out or irritate the skin. Combined with the allergenic potential of fragrance molecules, perfumes are among the most common triggers of sensitivity and barrier disruption.

This is why GEZEITEN formulas are entirely fragrance-free, keeping the focus where it belongs: on skin health, balance and long-term resilience.

Transparency is central to our formulation philosophy.

We include only ingredients that offer a proven benefit to the skin.

Yes. All GEZEITEN products are 100% vegan. We do not use any animal-derived ingredients in our formulas.

GEZEITEN is designed to simplify your skincare routine - fewer steps, deeper logic.

If you're new to our products, we recommend starting with one of our FACE CREAM LINES:
- LIQUID SKIN for sensitive, combination or breakout-prone skin, younger skin, or first signs of aging.
- INTENSIVE ANTI-AGING for mature, dry or demanding skin, or anyone seeking deeper nourishment, firmness and visible rejuvenation.

Then add serums according to your skin’s needs - for deeper, more targeted results:
- DAY SERUM Prevention & Protection in the morning to support protection, vitality and environmental resilience - preventing daytime stress before it impacts the skin.
- NIGHT SERUM Stimulation & Rejuvenation in the evening to enhance renewal, repair and overnight regeneration. Its senolytic-inspired formula helps target senescent cells for clarified, revitalised skin.

For periods when your skin needs extra support, after travel, sun exposure, stressful weeks, irritation or before a special occasion, our AMPOULES Skin Immunity Defense Treatment provide an intensive boost of resilience, clarity and recovery.

If you’re unsure which routine is right for your skin, our trained experts are happy to guide you at contact@gezeiten.com.

Yes. All GEZEITEN products are formulated with sensitivity in mind: microbiome-friendly, barrier-supportive and free from fragrance, phenoxyethanol and other common irritants. Our clean, minimalist ingredient philosophy makes GEZEITEN especially suitable for sensitive or reactive skin.

The NIGHT SERUM Stimulation & Rejuvenation contains a gentle, stabilised form of retinal (not retinol), which is generally well tolerated even by sensitive skin. If you are new to vitamin A, we recommend introducing it slowly - for example, using it 1–2 times per week and increasing as your skin becomes accustomed.

If you need help adjusting your routine or understanding how to use our active products comfortably, our expert team is here for you at contact@gezeiten.com.

Apply serums after cleansing:
- SERUM Prevention & Protection in the morning for protection against environmental and digital stressors
- SERUM Stimulation & Rejuvenation in the evening to support overnight renew

Yes. GEZEITEN is fully cruelty-free and complies with all EU regulations that strictly prohibit animal testing for cosmetic products, ingredients, and finished formulas. This means that neither GEZEITEN nor any of our suppliers or ingredient manufacturers conduct, commission, or permit animal testing at any stage of development or production.

Instead, we rely on modern, ethical and scientifically advanced testing methods - including skin cell cultures, 3D dermis models and skin explants. These technologies allow us to evaluate safety, tolerance and performance with exceptional precision while respecting both the skin and the environment.
At GEZEITEN, responsibly developed skincare is not a trend, it is a fundamental principle of how we formulate and innovate.

These modern testing systems enhance our Research & Development, providing us with unique expertise to better understand and identify the anti-aging, moisturizing, firming, and other benefits of our formulations.

Yes. All GEZEITEN formulas are developed according to non-comedogenic criteria.

Our ingredient systems avoid heavy, pore-clogging oils or occlusives and instead use lightweight, skin-compatible lipids such as squalane, meadowfoam seed oil and modern esters that support hydration without blocking pores.

Many of our actives, including niacinamide, zinc PCA, retinal, senolytic plant extracts, marine biotechnology and microbiome-supportive hydrators, help refine pores, regulate impurities and maintain a balanced, clear and resilient complexion.

For breakout-prone or combination skin, we especially recommend the FACE CREAMS Liquid Skin Line and SERUM Stimulation & Rejuvenation, which provide lightweight, non-pore-clogging hydration and barrier support.

If you need help building a routine for clearer skin, our expert team is happy to guide you at contact@gezeiten.com.

Yes, many GEZEITEN products are suitable for use during pregnancy.
Our formulas follow strict European safety standards and are created without many ingredients commonly avoided during this time.

All GEZEITEN day products are free from retinol and are considered pregnancy-safe.

For night care, the FACE CREAM NIGHT Liquid Skin contains Bakuchiol, a gentle, plant-based alternative to retinol that supports renewal without irritation and is generally well tolerated during pregnancy.

GEZEITEN does not use fragrance, essential oils, drying alcohols or other common irritant, fully aligned with our clean-beauty philosophy focused on purity, safety and science.

Because every pregnancy is unique, we always recommend discussing any concerns with your healthcare professional.

Our products are formulated to have a two-year shelf life when unopened and stored properly. Once opened, all of our skincare products have a recommended use-by date printed on the packaging, indicated by the "open can" icon. 9M stands for 9 months, 12M for 12 months, and 36M for 36 months. The quality of our products is only guaranteed within this period after opening.

At GEZEITEN, we do not focus on single-percentage claims because they say little about real efficacy or bioavailability.

A high percentage does not automatically mean a better result, it can simply be a marketing number.

What truly matters is how an active ingredient is:

• stabilised
• delivered into the skin
• combined with supporting actives
• absorbed and utilised (bioavailability)
• working in synergy with the skin’s natural rhythm

This is why we formulate with complex, multi-layered systems, where potent actives reinforce each other for maximum effectiveness and skin compatibility.

For example, a “10% hyaluronic acid serum” may sound impressive, but our 5% hydrating system can outperform it due to better molecular diversity, penetration, compatibility and formulation logic.

Instead of relying on empty marketing percentages, GEZEITEN focuses on intelligent formulation design that delivers proven, visible results.

If you would like personalised guidance on how our actives work, our expert team is here for you at contact@gezeiten.com.

GEZEITEN does not use retinol. Instead, we use Retinal (Retinaldehyde), a next-generation form of vitamin A with higher efficacy and better skin compatibility.

Retinal is included in:

• FACE CREAM Night Intensive Anti-Aging
• SERUM Stimulation & Rejuvenation

Retinal works more efficiently because it requires fewer conversion steps to become active in the skin, delivering visible rejuvenation faster and with greater precision than traditional retinol. At the same time, our stabilised, microbiome-friendly Retinal system is designed to minimise irritation, making it suitable even for sensitive skin.

For customers who prefer a routine without vitamin A, we offer a gentle, plant-based alternative: Bakuchiol, used in our Liquid Skin Night Cream, supports renewal and firmness without the typical sensitivities associated with retinoids.

This is why GEZEITEN chooses advanced actives: more performance, less irritation, and a smarter path to long-term skin health.

No. All GEZEITEN formulas are entirely fragrance-free.

We intentionally avoid perfumes - whether synthetic or natural - because fragrance molecules and their alcohol carriers are among the most common triggers of sensitivity, irritation and barrier disruption.

By removing fragrance altogether, we ensure that even sensitive or reactive skin can experience our products comfortably, with full focus on what matters: skin health, balance and long-term resilience.

GEZEITEN formulas are designed to be gentle, microbiome-friendly and suitable even for sensitive skin. Irritation is uncommon, and when it does occur, it is usually related to the introduction of active ingredients such as retinal or senolytic plant extracts, as the skin adapts to increased performance.

If you notice mild redness or sensitivity, simply reduce usage or take a short break to allow your skin to rebalance. This adjustment phase is normal and typically temporary.

You are never alone in this process: our trained expert team is happy to support you with personalised guidance at contact@gezeiten.com.

If you already know that your skin reacts to specific ingredients or if you have allergies, feel free to contact us before starting a new product, we are here to advise you. You can also review the full, always up-to-date INCI list on each product page, allowing you to make informed decisions with confidence.

If irritation persists, we recommend consulting your dermatologist.

All GEZEITEN products are developed and manufactured in Germany under strict European quality, safety and regulatory standards. Every formula passes through controlled, carefully monitored production steps to ensure purity, stability and performance.

Our active ingredients, especially our marine biotechnology, are sourced and developed with our scientific partners in Brittany, France, a region globally recognised for innovation in marine science.

All packaging is produced in Europe as well, ensuring responsible sourcing, traceability and full alignment with our sustainability and quality principles. Nothing is mass-produced; every component is intentionally selected and rigorously tested to meet the high standards that define GEZEITEN.

You should feel the quality of GEZEITEN immediately - our formulas are designed to deliver instant comfort, hydration and a more balanced, harmonious skin sensation from the very first applications.

As your skin adapts to the chrono-adaptive system, it naturally becomes more even-toned, stable and radiant. Deeper results, improved firmness, refined texture, reduced hyperpigmentation and softened fine lines, typically develop within one full skin renewal cycle (around 4 weeks).

We believe in science over shortcuts.
Fast, aggressive solutions may sound tempting, but they often lead to long-term imbalance: a weakened barrier, sensitivity or rebound pigmentation. GEZEITEN takes the opposite approach - we work with the skin, not against it, to create results that are both visible and sustainable.

Every skin is unique, but one principle remains true: consistency creates transformation. Staying with your routine allows the full potential of our formulas to unfold.

If you’d like personalised guidance for more consistent results, our expert team is here for you at contact@gezeiten.com.

GEZEITEN can be integrated into most routines - however, our serums are high-potency, multi-level formulations with up to 15 synergistic active ingredients. Because they already deliver comprehensive performance, we recommend not combining them with additional strong actives (such as acids, retinoids or intense exfoliants) from other brands.

Our philosophy is simple:
work with the skin and its natural intelligence - supporting, activating and balancing it according to its rhythm.
Overloading the skin with competing actives can disrupt this balance.

If you are currently using highly active products from other brands, introduce them slowly, alternate usage, or let us review your routine.

Our expert team is happy to provide personalised guidance at contact@gezeiten.com.

Yes, GEZEITEN formulas are gender-neutral, performance-driven and suitable for all skin types.

Male skin is often slightly thicker, produces more sebum and can experience sensitivity from shaving. Our microbiome-friendly, balancing and barrier-supportive formulations are especially helpful for reducing post-shave irritation, strengthening resilience and keeping the skin smooth and hydrated.

Many men appreciate our streamlined, high-performance approach - fewer steps, powerful results, and textures that absorb quickly without residue.
