Leather - the main character of any beauty blog and probably the best natural indicator of our health. If we have bad suddenly started to work any internal organ, the skin immediately signals to us in the form of rashes, acne, blackheads and comedones.
From the textbooks of anatomy and special literature on Cosmetology will know what kind of our skin hard worker. It operates 24 hours 7 days a week. Afternoon - protects us from ultraviolet radiation, harmful microorganisms, dust and other "intruders" from the environment. At night, instead of relaxing the skin actively updated to once a day to protect all that is hidden underneath, from external elements outside and overheating.
Here are some facts about our toiler, after reading which you more than usual began to respect your skin and will take good care of her.
№1 fact. Leather work qualitatively climate control in the expensive car
Throughout our lives the skin keeps a temperature through two mechanisms: blood circulation and perspiration. In hot weather, the vessels in the skin sweeps 8 liters of blood per minute. The result is comparable with the normal water pressure of the tap.
In our bodies every second to make many (from metabolism to transport minerals to all parts of the body), it still requires energy. Even during sleep, our body recovers, and it also takes a lot of energy (not just same as waking up and getting on the scale we see the weight that is less than when we weighed before bedtime). Every 15 minutes, our body temperature is increased by 1. Were it not for the skin, our blood and all protein structures would be folded in 2 hours, we would have simply died.
Therefore burns over 50% of the body is extremely dangerous to humans. Burnt skin, people kind of sane, normal answer questions and did not even feel any pain. But after an hour or two the state of his body becomes extremely difficult. And the chances of survival are minimal.
Blood hot within us, and in the skin it is passing through the vascular network, it is cooled through sweating. Perfect natural climate control of our body! And remember that if after jogging in hot weather with you flowing in buckets or treadmill in bad ventilated room after you all slippery with sweat - proud that you have such a "great heat-transfer the car".
№2 fact. Skin sheds a lot of dead skin cells, but is not updated within a month
On this fact, I would like to elaborate. In the literature on cosmetics is not the first freshness walking is the fact that continually skin "resets" itself to 40 thousand. squamous cell. And to complete its update requires 28-30 days.
In order that the skin is momentarily resets to several thousand dead epithelium - rightly, the main proportion of dust in the house constitute the dead cells of the epidermis (outer skin and a protective layer). But The second assertion is misleading. Knowledge of cosmetology accumulate, much has changed. Plus, people are asking the right questions: "If my skin is completely updated this month, why after a month, my skin does not become beautiful, perfect and brand new? Why, then, are relevant peeling means, once the skin is able to rid itself of squamous cell?".
Previously it was assumed that the epidermis is composed of two types of cells: keratinocytes and melanocytes. Keratinocytes make up 80% of all cells of the epidermis, or create and maintain the protective function of the skin. Melanocytes produces pigment and colors our skin (they just dictate what we will be skin color, hair color and decide whether to be a hyper-pigmentation on our skin or not).
New in Dermatology following data:
1) keratinocytes live 8-10 days, they are programmed by nature to extinction. However, keratinocytes unlimited resource of stem cells, so they are constantly updated, updated and "push" the old keratinocytes in the stratum corneum. Keratinocytes, by the way, are hydrophobic cells: this means that they repel water, we clearly see if a drop of water applied to the skin, it just rolls down and is absorbed. So that moisturize the skin with water alone can not require the substance-conductors;
2) The melanocytes in our skin about 7%. Generally, they are formed around the cells of the nervous system, then "scatter all over the body": the skin, hair and eyes. Melanocytes form a pigment. To the lower layers of the epidermis they dragged keratinocytes. They do not have stem cells, but they are very long-lived. May be even a lifetime. As you have seen, less than those living melanocytes, which are found in the hair (gray hair there is a lack of melanocytes);
3) there are two types of cells: Langerhans cells and Merkel. Langerhans cells - a super-defenders in the epidermis, produces their bone marrow, and if a foreign body falls inside the epidermis, these guys capture intruders and carry to the lymphocytes in the dermis, which is a foreign body destroyed. Each cell lives longer than a month. Merkel cells are placed around the hair follicles, they just are responsible for the sense of touch: thanks to them, we are clearly aware of touch, cold, heat, etc. They are long-lived cells.
Thus, the complete renewal of the epidermis of the month - it does not even mean the hospital. Some cells live for up to 10 days, the other - a little more than a month, and some not at all updated throughout our lives.
№3 fact. The skin can also have an orgasm
This phenomenon even has a scientific name - piloarrektsiya.
The muscles under the skin are reduced, thereby raising the hair and lead to the formation of "goose bumps" (on a simple - goose). This feeling is familiar to all of us, when we liked any song, a fragment of the film, or by touching a loved us human.
Now that you know the name "skin orgasm" :-)
№4 fact. Where the smell - the alkaline environment
Our skin acidity level (pH) varies 4,7-5,5. This acidic environment. But in a soap solution is pH 9-11. This alkaline environment.
Odorous cancer of the genitals, buttocks and underarm skin pH change towards alkali. That is why for such zones do not use alkaline soap and acid agents. In such places microflora generally very fragile and, if knocked pH towards the alkaline medium, the microflora becomes more vulnerable to harmful bacteria.
№5 fact. The epidermis around the eyes twice thinner than office paper
Bit arithmetic: the stack of paper for a printer having a thickness of 50 mm, in the pack - 500 sheets, for a total thickness of one sheet is (50/500) = 0.1 mm. The same thickness of our epidermis (except for the working areas - the hands and feet, where skin is slightly thicker). A thickness of the epidermal area around the eyes was 0.05 mm, and it is 2 times smaller than the thickness of copy paper sheet. Not just advise to put money on this area carefully and not to stretch the fingers.
Leather - hard worker, and our protector. But one of its natural structure of such a complex will not be enough to make it qualitatively worked for us all his life. Behind it needs care and proper nutrition. Take care of yourself, and in particular your skin :-)
