Have you ever wondered if the age-old advice of getting your beauty sleep has any scientific backing? Well, the answer is a resounding yes! Night time is your skin’s rejuvenation period, and can make a world of difference in your skincare routine.
Recent research has shed light on the fact that our skin, much like the rest of our body, operates on a circadian rhythm. In simpler terms, it knows when it’s night and day. A study published in the Journal of Investigative Dermatology found that the expression of certain genes related to skin health follows a circadian pattern, influencing various functions throughout the day.
This rhythm plays a crucial role in orchestrating the various cellular activities that happen during different times of the day, regulating stem cell functions and impacting the regeneration process.
What Happens When We Sleep?
One of the key processes that occur is cellular turnover. This is when old or damaged cells are replaced with new, healthy ones. Skin cells, including keratinocytes, fibroblasts and melanocytes, repair and regenerate damaged tissue. In fact, the peak of cell proliferation and turnover occurs during the late night and early morning hours. Furthermore, the increased blood flow to the skin ensures the delivery of essential nutrients and oxygen to skin cells. This boost in circulation supports the repair and regeneration processes, contributing to a healthier and more vibrant complexion.
Collagen, the superhero protein responsible for maintaining skin elasticity and firmness, takes centre stage during the night. Its production increases while we sleep, aiding in the repair and strengthening of the skin’s structure. Additionally, our complexion gets a respite from environmental stressors such as UV radiation, pollution and temperature fluctuations. With reduced exposure, it can focus on repair without external interference.
Crafting The Perfect Night-time Routine:
To harness the benefits of night time skin rejuvenation, start with a thorough cleanse to rid your skin of the day’s impurities, allowing it to breathe freely. Follow up with a nourishing moisturiser – like Radical Night Repair from Zo Skin Health – that improves texture and uneven pigmentation, and minimises the appearance of fine lines.
Don’t stop there! Incorporate targeted treatments such as serums or masks to address specific concerns like hydration, anti-ageing, or brightening.I love Zo’s Firming Serum – a mild, lightweight and tolerable formulation for all skin types that supports the visible improvement in skin elasticity and firmness.
And don’t forget the delicate eye area, ensuring a radiant and well-rested glow when you wake up. It’s particularly susceptible to signs of ageing, so keep Zo’s Eye Brightening Crème close to hand. It’s specially designed to help minimise signs of ageing, including puffiness, dark circles and fine lines.
