The skin: an organ in "biorhythm" mode

Just like our bodies, our skin is subject to a circadian cycle. This 24-hour cycle determines when the skin is in defense mode against external aggressors and when it is regenerating. During the day, the skin forms a protective barrier against aggressors such as UV rayspollution and blue light from screens. It tightens to minimize external damage.

At night, however, everything changes. The skin goes into repair mode. Skin cells divide and regenerate up to three times faster than during the day. Blood microcirculation increases, bringing more oxygen and nutrients to the epidermis, promoting the creation of new cells and the development of new cells. collagenIt's also the time when pores open up, allowing skin care products to be better absorbed at night.

This leads to premature aging, with skin losing its suppleness and becoming more vulnerable to external aggressors.

The benefits of sleep for the skin

A good night's sleep allows the skin to regenerate in depth. During the night, production of collagen and elastin increases, proteins essential for skin firmness and youthfulness. Dead cells are eliminated, and new cells take their place, ensuring a brighter, more even complexion in the morning. Blood microcirculation, optimized during sleep, gives the skin a fresh glow and better hydration.

What's more, between midnight and 4 a.m., skin is more permeable, making it more receptive to skincare products applied before bedtime. This is the ideal time to use creams or serums rich in regenerating active ingredients like hyaluronic acid or retinol.

Impact of sleep deprivation on skin aging

Studies show that people who get too little sleep are more likely to show signs of premature aging, such as wrinkles, fine lines, sagging skin, and pigment spots. These signs are exacerbated by reduced collagen production and poor blood circulation due to lack of sleep. What's more, tired skin is more likely to show signs of oxidative stress, a process that accelerates skin aging.

How can you optimize your sleep for radiant skin?

There are several tips for maximizing the benefits of sleep for your skin. First, make sure you get between 7 and 9 hours of sleep a night. Adopt a routine to synchronize your biorhythm.
