Circadian rhythms and cosmetology
The skin is not just a barrier structure, it takes an active part in maintaining the homeostasis of the entire body
Our planet has cyclically stable changes in photoperiods — annual and daily. This periodicity has existed for millions of years and has led to the emergence of a mechanism that controls changes in the body that occur when lighting conditions change during the day. Thus, organisms have developed “biological clocks” determined by a genetic program, or circadian rhythms (CR), which determine the rhythms of the biochemical, physiological and behavioral activity of all life on earth.

We started talking about CR in the previous article.
In this part we will talk about circadian rhythms in cosmetology, their possible impact on the effectiveness of aesthetic therapy results.
The study of the relationship between circadian rhythms and health led to the creation of chronobiology — a science that studies the biological rhythms of living organisms, promising opportunities for restoring the central nervous system when they are disrupted. And perhaps ensuring the prevention of their violation. It should be noted: in winter there is a shift in biorhythms by an hour. The activity of skin functions in the light of chronobiology can be represented in the form of daily biorhythms. Although this is conditional, knowing about CR is useful for practical use, since the protective activity of the skin predominates during the daytime, and the revitalizing activity of the skin predominates during the night.
Let's take a closer look.
4:00-5:00 — the body prepares to wake up. The formation of hormones (cortisol and adrenaline) increases, and blood sugar levels rise. During this period, the skin may experience swelling in the face and eyes.
6:00-7:00 — the body wakes up. The protective function of the skin increases, the activity of the antioxidant system of the epidermis reaches its maximum. The formation of the epidermal barrier begins. At this time, it is recommended to cleanse with soft, delicate products in the form of milk or foam, which contain a natural moisturizing factor, glycerin, vitamin E, bisabolol, and almond oil. If you have sensitive skin, you can use tonics as a cleanser, which will contain a natural moisturizing factor, allantoin, urea, and glycerin.
