The importance of nighttime skin care and how to do it well

Jan 27,2022 | HISEEK PRETTY

During the day, the human body faces multiple threats from the environment, such as sunlight, stress, and smog. During this time, the skin develops its protective function against these threats.

In the evening and night, the skin regenerates. Since the skin appears to be more reactive and permeable at night, these effects can be used to optimize the delivery and efficacy of cosmetic and medical activities.

However, many people find that they are prone to acne and bad skin tone after staying up late. In this article, we will talk about nighttime skincare and lifestyle habits

Scientists have discovered the molecular mechanism that controls the circadian rhythm. That is, they looked at how what we commonly call the biological clockworks. They isolated a gene that controls the normal circadian rhythm of organisms by using experimental methods such as fruit flies. They found that the gene encodes a protein that aggregates inside cells at night and degrades during the day.
The above may be too obscure, let's take an example to illustrate the biological clock and circadian rhythm:

As shown in the figure, the biological clock in the body still works in different periods of time. The biological clock is a very precise thing that can adapt the biological mechanism of the organism to different periods of the day. Likewise, humans are precisely influenced by the biological clock, which helps us prepare our physiology for the fluctuations of the day. The biological clock regulates some of our key functions, such as when you feel like you are going to sleep, changes in body temperature, the speed of metabolism, and even the level of hormones, which in turn affects your willingness to do indescribable things at night; There is also a more intuitive performance, such as returning from Europe, you have to have a jet lag, etc.

Disturbance of the body clock can also bring about various consequences such as depression, obesity, and so on. So the skin works 24 hours, so skincare should also be done 24 hours. However, the environment of day and night is different, and the state of people is also different, and some distinctions can be made in the focus of skincare.

Daytime skincare: sun protection, hydration, and antioxidants

Daytime skincare should focus on helping the skin to strengthen its defenses. In general, daytime skin needs to withstand the challenges of UV rays, makeup, air pollution, and work stress. Therefore, sun protection, moisturizing, and antioxidants are all important.

As the three basic skincare brothers, the appearance rate of cleaning, moisturizing, and sun protection is really high, and I believe our fans are already familiar with them. In fact, in the eyes of dermatologists, the fourth point of skincare must be antioxidants.

When we talk about antioxidants, we are actually talking about resisting "oxygen free radicals". A free radical is a chemical concept that refers to an unstable group formed after a molecule is broken. It can achieve a stable state by robbing other atoms of electrons.

Once the skin is in an excessive oxidative environment for a long time, many problems will occur, such as photoaging caused by ultraviolet rays, which is closely related to oxidative stress.

Then, the phenomenon of pigmentation, dullness, fine lines, sagging, sagging, and even sagging will line up one by one, holding the old number plates, and come to people's faces.

The most dangerous molecule that affects free radical levels is UV light. Ultraviolet light is very energetic and can turn otherwise stable molecules into unstable free radicals.

So I have to emphasize again: anti-aging ten million, sunscreen first. Of course, it is difficult to achieve 100% sun protection. If you do a good job of anti-oxidation at the same time, after ten years, your skin will definitely thank you.

In addition, high stress, poor sleep, poor mood, etc. will also release more free radicals and accelerate skin aging by affecting the mitochondria inside cells.

Therefore, after controlling the "foreign thief" of ultraviolet rays, we must also beware of the "horse thief" of pressure. As a human being, the most important thing is to be happy.

In short, the sun is stronger during the day, and the work pressure will be greater, which is a period of free radical growth. Therefore, during the day, we can use antioxidant products in addition to our regular skincare.

Nighttime Skincare Focus: Moisturizing and Antioxidant

At night, the water loss rate of facial skin is faster than that during the day. For example, the fastest water loss rate in the forehead is 12:00 in the morning, and the water loss rate can be about 3 times that of noon. Based on this, we can know that nighttime skincare at least To do a good job of moisturizing, make sure to fall asleep before 12 o'clock.

On the other hand, the barrier function of the skin deteriorates at night and the blood circulation is accelerated, so this time is theoretically the golden period to promote the absorption of active ingredients in skincare products. Therefore, the products used can be functional products that contain more nutrients that are useful to the skin.

Therefore, friends who have anti-aging needs can regard anti-oxidation as the focus of night skincare. After all, as long as people live, they are producing free radicals. 24/7 skin also needs full day + night antioxidant care.

So what can we do for nighttime skincare to better match our skin's circadian rhythm?

▲ First of all, we need to have the concept of night skincare. Going to bed after washing your face at night and applying nothing will not have a good future.
▲Second, at least moisturizing, because according to the circadian rhythm, the facial skin will dry at night, especially if it is in an air-conditioned environment.
▲In addition, choose some skincare products with anti-oxidation and anti-inflammatory properties, or special big-name and excellent products for nighttime. While repairing, it can also have more nourishing functions, such as a variety of vitamins, amino acids, polypeptides, and other nourishing and repairing ingredients. For nighttime, according to the various indicator data displayed by the circadian rhythm of various skins, the effect should be better than during the day.
▲ Don't think that good night masks, sleeping masks, good night gels, etc. must be good products for the night. In many cases, these products are just moisturizing products.
▲ Use sunscreen during the day, otherwise, the DNA damage caused by ultraviolet rays will become more and more difficult to repair at night with age.
▲Few of the night food stalls and late-night snacks. If you want to be beautiful, you have to keep your mouth shut.
And most importantly, don't stay up late, sleep well. Go to bed before 11!

You asked if there is any actual case to prove it, I believe that many over time dogs must have experience. In addition, some people abroad have done some sharing of the effect on the skin after the sleep time is shortened. for example:

To sum up: Scientific skincare and good living habits are also the circadian rhythms of the human body that let us cooperate, so that the skin can achieve perfect transformation efficiently.
