For someone now would be a sensation, but for dry and dehydrated skin advice "drink plenty of water" will not help. Moisturize the skin - not an easy mechanism.
You think, went to the shower, the water will seep into the lipid barrier and everything - the skin moisturized? Not. Salt tap water only further stretched water molecules from the lipid barrier.
With the shower sorted out, just sprinkle some water themselves and thus to restore the lipid barrier fail. Yes, and for many it is an obvious and long-known fact.
And what advice "drink lots of water and your skin will shine"? After all, his shoved wherever falling: in glossy magazines, in a comment under the post about dry skin.
Of course, our water is vital: without it, our bodies would not be able to pass any normal exchange process (oxidation, hydrolysis, etc.) to increase the friction between the joints and internal organs, the entire digestive system will be bent, wither with it, and kidneys. We have no water simply will not survive, it is obvious.
Here only in respect of the skin no more scientific evidence that "the more you drink the water - the better hydrated skin".Disputes about the importance of the amount of alcohol consumed drinking water in the hydration of the skin do not cease among doctors. However, no one disputes the fact that the drinking water supplied by the body first in all the internal organs and the skin comes last in the queue. And no one disputes the fact that the lack of hydration leads to tightness, flaking and dryness of the skin.
We have reached a consensus: if you drink at least 8 glasses of water a day, it is possible that the skin will shine. But what exactly is worse.
Not the amount of water you drink to solve the moisture and fat
You can drink at least 5 liters of water a day, but if in the lipid barrier is low in fat - the water in the skin will not held, it evaporates, it is necessary to uncork another 5-liter PET bottles with drinking water and to choke her.
Our upper skin layer (epidermis) - a kind of a brick wall, the protective barrier. He does not pass into the deep layers of the skin the fine particles from the environment: dust, dirt, bacteria and other microorganisms.
In the role of a protective barrier of our bricks are the dead horny scales. Cement for these blocks are intercellular lipids.
Lipids - fats is. So what is the connection between fats and moisture? Fats moisturize? Not! But lipids fulfill a different role (and very important for the skin) - they inhibit the trans-epidermal water loss.
To understand the importance of lipids in the moisture, it is necessary to understand approximately how all the water gets into the epidermis.
Thus, the water comes from deep in the epidermis and the living layers of the skin. Skin layers deep water supply blood vessels (By the way, one of the reasons why massage and other techniques to improve blood circulation and improve skin tone make it even better).
Water is supplied through the blood vessels in the dermis, then - in the epidermis. Next - it evaporates. This process is continuous, and that our "brick wall" was strong, there must be a sufficient amount of lipids that will keep the water balance in the skin.
Now gradually move to serious guys who can attract moisture from the air and hold it. This gang has its own name - natural moisturizing factors (Natural Moisturizing Factor, abbreviated - NMF). Their hygroscopic sponge like molecules attract moisture from the air, it is held on the surface of the stratum corneum, thereby moistening it and do their work better hyaluronic acid.
NMF have in our body, but they are not enough. They also work well when applied externally. As you understand, we are talking about our favorite moisturizers kremikom.
If we plan to stock up on cosmetics for the purpose of quality moisten the skin, then it is necessary to know the basic components of the natural moisturizing factor. And it is with us:
- amino acids (Of which NMF Comp almost half) is glycine, serine, alanine, betaine, glutamic acid, proline, threonine, lysine, etc .;
- pyroglutamic acid (On the label, usually written in Latin abbreviation PCA, pyrrolidone carboxylic acid) as well as all of its salt (Na PCA and Sodium PCA);
- His Majesty glycerol (Afraid of this fellow on the labels, especially when it comes to second place in the lineup, and a very good reason);
- lactic acid (Lactic acid) and its salts (sodium lactate);
- sodium ions, chlorine, magnesium, calcium, potassium and phosphate;
- urea (But about it I have large separate article);
- peptide complexes, and complexes of organic acids and sugars.
It is believed that if to remember all of the above, the composition of beauty products in the future will be easier to read for humans.
The natural moisturizing factor - it's very big and interesting topic. If you are interested in this column, then put his finger up to the article - I'm happy to continue on its material.
