THE BENEFITS OF A GOOD NIGHT SLEEP
To have a “restful sleep” becomes very meaningful when it comes to the beauty of our skin. After a sleepless night, or just too few hours of sleep, our skin gets dull, we look tired and not healthy anymore. And this is entirely normal, because our skin has not had enough time to repair and regenerate properly.
Often neglected, sleeping habits play an essential role in the appearance and health of our skin. Let’s review all their benefits now!
The chronobiology of the skin
Our skin follows a day-night schedule, like our whole-body system. It is called “cutaneous chronobiology” or “skin biorhythm”. It means that our skin functions differently along the 24 hours of the day, alternating phases of high and low activity. Daylight intensity being the main trigger to these changes, our skin just follows its work schedule day after day, relying of the alternance of day and night. This mechanism is written in our genes and guides all the activity of our body organs.
In the morning, the skin is in defense mode. It acts like a protective barrier against aggressors like pollution, sun, wind, dust particles or blue light. Cutaneous cells shrink and stick closer together to form a shield.
When the night comes, the skin switches to a clean-up and regeneration mode.
What does our skin do at night?
At night, our skin is “at rest”. But it does not mean that our skin does nothing! It means that our skin is, theoretically, not targeted by aggressors anymore and can use that time to peacefully repair itself.
Skin regeneration happens through a process of cellular division. At night, skin cells multiply themselves up to 3 times more than during the daytime!
To allow this cellular renewal, our skin needs energy brought by our blood. There is indeed an increase in blood microcirculation. Our skin then becomes more permeable and opens its pores, which is the exact opposite mechanism to the daytime shield process we talked about earlier.
The benefits of sleep for the skin
After a good night sleep, our skin has regenerated et created enough collagen and elastin. The cellular renewal and the accelerated microcirculation have resulted in a fresh complexion and a reduction of dark circles when morning comes. The skin is also better oxygenated.
The higher permeability of the skin between midnight and 4am allows skin products to penetrate deeper and give better results.
Before going to sleep, properly cleanse your skin to remove all impurities accumulated during the day and apply your night cream. The chrono-regenerating blue balm Blue Techni Liss Nuit helps our skin keep up with its day-night schedule and use all the benefits of obscurity to regenerate and start strong on the following morning. Formulated with extracts of blue chasteberry, an ancestral plant rich in phyto-endorphin, this night cream helps our skin fight the de-synchronization of our natural biorhythms.
