Understand the field of circadian rhythm & its implications across to your day.

We all follow a 24hr daily (circadian) rhythm, controlled by biological clocks - the master one being in the brain.

This clock is responsible for setting the programme for all of your bodily functions (temperature, hormone release, metabolism, sleeping and cognitive function) to be more efficient at certain times of the day. To ensure that your skincare and wellness solutions are delivering exactly what your skin needs - at exactly the time it needs it - This Works have spent a great deal of time working with experts in the field of circadian rhythm to understand its implications across a 24hr period.

What does the circadian rhythm control?


Behavioural manifestations such as the sleep-wake cycles are also controlled by the clock - and it is important to note that, unlike normal clocks, your biological clocks are not synchronized and do not keep the same pace.


Late at night and early in the morning, while we sleep, the epidermal (or skin) stem cell creates new cells, replacing the aged ones. This happens when the body is supposed to be at rest and not disturbed - hence the importance of keeping a sleep-wake schedule.


The skin barrier is the first line of defence for the body against microorganisms and environmental factors. Throughout the day, the skin cells operate different activities to protect and defend the body - hence why the skin is more sensitive at certain times.


Skin hydration is necessary to maintain a protective barrier against infection and dehydration. The water content of the skin has a daily rhythm, with minimum loss (through the pores of the skin) in the morning and an increased water loss during the night.


The skin has glands that produce sebum, which waterproofs and lubricates the skin and hair. Sebum excretion peaks around midday, with the lowest levels in the late evening and the morning.


Skin cells also have their own clocks, which can function autonomously. Many external environments may also reset these clocks (pollutants, temperature, humidity, ultraviolet radiation).

This Works is a clean, targeted skincare brand that works in harmony with your body clock to maximise skin performance 24 hrs a day, starting with a good night’s sleep. They divide the 24hr day into four phases, NIGHT, WAKE-UP, DAYTIME and EVENING, based on their understanding of how to enhance the skin’s natural processes.

Let’s take a closer look at the Night and Wake-Up phase and how they effect your body and skin;


sleep & repair

  • Repair mode is activated
  • Skin’s dehydration levels peak (Due to trans-epidermal water loss)
  • Production of Melatonin (the sleep hormone) is at its highest
  • Anti-inflammatory and anti-stress hormones are released
