Fun fact: cosmetics work best at night. But why ?

Creams, masks, serums, eye contours, care oils… More and more cosmetics are mentioning “night care”. But how are they more effective than their peers in kindergarten? Is it an extra marketing argument or a real revelation in terms of beauty routines and cosmetics? And why do we give so much credit to the night? We answer you.

At night the skin does not rest, it regenerates

You never noticed how the skin looked more supple, plump and radiant after a good sleep ? Do you think it was a coincidence? Well no!

During the day, in fact, he takes care of the skin defend itself from the various attacks it can suffer. Wind, pollution, sudden changes in temperature, cigarette smoke, contact with bacteria on our hands… It has a lot to deal with to stay healthy.

And even if she burns like crazy, she doesn’t indulge in idleness during the night: her main concern is activate its cell regeneration mechanisms. The target ? Dermatologist Marie-Pierre Hill-Sylvestre interviewed by Psychology journal explains it very simply:

“This renewal is actually a process of cell division. Skin stem cells divide in two. One gradually rises to the surface to fulfill its functions and then disappears in the form of a stratum corneum; the other remains in its place and regains strength to be able to divide again. »

At night, the skin absorbs 100% of the cosmetic active ingredients

From the skin is more available during the night, its ability to absorb skin care active ingredients is increased tenfold. Thus it reaches its climax at a precise moment according to Marie-Pierre Hill-Sylvestre:

“The multiplication of epidermal cells is maximum at 1 in the morning, minimum at 13:00. »

At one o’clock in the morning, the skin’s absorption capabilities can reach 100% — if and only if it is exfoliated regularly. Because when it’s not, impurities and sebum clog pores. As a result, the active ingredients have a harder time passing through and cell regeneration is more complicated.

Are night care products more effective than others?

So, in your opinion, are we talking about a marketing bluff or not? We would like to give you a precise answer but in reality it is: Yes and no.

Yes because cell renewal will take place very properly with your daily care. And not because it should be admitted that the treatments dedicated to the night are often more dosed in active ingredients compared to their daytime counterparts. Their ingredients are sometimes even chosen with a magnifying glass to be able to embrace the mechanisms of the skin during sleep…

So it’s up to you to see which team you will play for.
