What’s the secret to waking up with beautiful skin?

Scientific studies on our body’s natural circadian rhythms have shown the importance of deep sleep on skin quality.

Want better skin? Get a good night’s sleep

Our body has an internal clock that operates on a 24-hour cycle called “circadian rhythms.” These rhythms orchestrate a number of biological changes, including fluctuations in normal cell function and hormone levels that affect not only our bodies but our skin as well. During the day, the skin must defend itself against all sorts of environmental aggressors – wind, sun, cold or even pollution. When night falls, it’s the time for skin to regenerate and repair itself in preparation for the next day.

Irregular or poor quality sleep can disrupt the balance of circadian rhythms and, in turn, affect skin quality, resulting in drawn features, a dull complexion and more noticeable redness.

The night life of your skin

Did you know? The following skincare repairs take place while you sleep, affecting how your skin looks and feels in the morning.

1. Cell regeneration intensifies

Studies have shown that cell division increases overnight, reaching a maximum between midnight and 1am. This important regeneration process is crucial for more healthy-looking and more resistant skin.

2. Microcirculation accelerates

Blood flow to the skin increases at night due to a peak in skin cell exchanges, which either provide nutrients or eliminate toxins. Not only does this process increase cellular energy levels, it also leads to a more even complexion.

3. Cell turnover increases

The outermost layer of the epidermis is made up of dead skin cells. Every four to six weeks, these cells are eliminated from the skin’s surface in a process known as desquamation. Studies have shown that this shedding process on the surface layer of the skin reaches a maximum at night, making way for a smoother skin.

4. Skin’s protective barrier repairs itself

This intensive nighttime cell regeneration process increases the permeability of the skin barrier. It allows the skin to eliminate toxins, but also leads to a decrease in the skin’s moisture levels. At the same time, cell differentiation, microcirculation and desquamation all increase to help the skin prepare itself and restore its protective barrier, leading to a more resistant and hydrated skin all day long.

There’s a reason it’s called beauty sleep! The next time your skin is lacking its luster, remember the replenishing effects of a good night’s rest. And for those occasional sleepless nights, rest assured that scientists have created cosmetic solutions to simulate the effects of good quality sleep on your skin.
