Understanding Skin Chronobiology:
Tailoring Skincare to Your Natural Rhythm

Your skin follows a natural, internal clock, known as its biorhythm, which influences how it reacts to environmental factors and how it regenerates throughout the day and night. Understanding this process can help you optimize your skincare routine, ensuring that you’re using the right products at the right time to support your skin’s natural functions.

At GEZEITEN Skincare, we harness the science of chronobiology, which studies how biological processes align with the time of day. Let’s break down your skin’s daytime and nighttime processes, and discover how you can tailor your skincare routine for maximum effectiveness.

Daytime

Focuses on protection

hydration

shielding from external aggressors

Nighttime

Dedicated to skin repair

regeneration

detoxification

DAYTIME SKIN PROCESSES:
THE SKIN’S DEFENCE MECHANISM

Your skin’s natural defense systems are most active during the day. The external environment puts your skin through various challenges, such as UV exposure, pollution, and stress.

Chronobiology helps us understand how the skin adapts to these factors throughout the day, enabling us to use skincare products at optimal times for protection.

6 AM - 8 AM: Skin Awakens

  • Skin barrier is at its strongest, helping to protect against environmental stressors.
  • Sebum production begins, providing natural oils to maintain hydration.

8 AM - 12 PM: Defense Mode

  • Antioxidant activity increases to protect against free radicals from UV rays and pollution.
  • Blood flow decreases as skin shifts focus from repair to defense.


12 PM - 3 PM: Peak UV Stress

  • Skin faces its highest exposure to UV rays, pollution, and blue light.
  • Sweat and oil production increase to cool and protect the skin.


3 PM - 6 PM: Energy Dip

  • Skin’s natural moisture levels begin to drop as the day progresses.
  • Skin may feel fatigued due to accumulated stressors.

NIGHTTIME SKIN PROCESSES:
REPAIR AND REGENERATION

As your skin unwinds for the night, it switches to recovery mode, focusing on repair, regeneration, and detoxification. Nighttime is when your skin works hardest to repair itself from the damage accumulated throughout the day.

Here’s a breakdown of your skin’s nighttime biorhythm and how to support it with the right products.

10 PM - 12 AM: Repair Begins

  • Cell regeneration starts as skin enters recovery mode.
  • Blood flow increases, delivering nutrients and oxygen to repair skin damage.


12 AM - 2 AM: Peak Repair

  • Skin’s cell turnover is at its highest, shedding dead cells and generating new ones.
  • Collagen production increases, helping to repair damage from UV exposure and stress.
  • The skin barrier strengthens as repair work continues.


2 AM - 4 AM: Detox Mode

  • The skin’s lymphatic drainage system is activated, removing toxins and waste.
  • Oxidative stress is repaired, counteracting free radical damage from earlier in the day.
  • Hydration loss occurs, so it’s essential to replenish moisture.

4 AM - 6 AM: Recovery Slows

  • Skin processes wind down as it nears the end of the night.
  • Inflammation can peak as cortisol levels rise in preparation for waking, potentially causing puffiness.
