Water makes up about 60% of the body. It is not only a key component of blood and other body fluids, but is retained in all tissues. The cytoplasm of the cells and cell walls contain an enormous amount of water. The skin acts as a water tank, but nevertheless often becomes dry and peels off. What is the reason?
Each day evaporates through skin approximately 110-220 milliliters of water, and we didn’t even suspect. Intake of fluids in large numbers helps to replenish water in the body, but does not guarantee the smoothness and elasticity of the skin. Water balance in the tissues is regulated by chemical reactions and is not directly connected with the amount of water we drink.
If water can be applied to the skin as a cream, it’s also not too would have helped. After a bath or shower you feel that your skin is soft and fresh: this happens because the stratum corneum (outermost layer of the skin), formed by the omertvevšimi cells of the skin, absorbs water.
While bathing the skin absorbs up to 60 millilitres of water. However, the water is delayed in surface and does not penetrate deep into the skin. Within ten minutes later all the absorbed water evaporates, and the skin becomes dry again.
Our skin has a natural mechanism for preventing dryness and moisture retention. Skin cells generate specific protective layer, which consists of fats, amino acids, sugars and other compounds, soluble in fat or water. Together, these components form a chemical bond with water and thus prevent its evaporation. The water that is held by a protective layer of skin is absorbed by the cells of the stratum corneum. The skin becomes soft, smooth and elastic.
Too hot or cold air, low humidity, frequent contact with water or cleaning solution destroys this protective layer, and the skin loses its natural ability to retain moisture. If you demote the water content at 10% of the skin becomes dry, flaking, itching.
As we age, the body’s defense mechanism of the skin, and the skin is getting weaker all the more dry. Some people are prone to dry skin by inheritance-she lies in their body.
Ways to protect your skin
Despite the fact that the top layer of skin cells, the omertvevšimi was formed, we have to care about it and to provide proper care. The original function of the corneal layer protecting the deeper layers of the skin, where a generation of new cells. Regular use of moisturizers helps prevent fluid loss, restore the water balance and elasticity of the upper skin layer that enhances its effectiveness.
Oils, fatty acid and mucopolysaccharides are widely used in cosmetic products, because they help prevent dry skin. For this purpose, the most suitable and effective cosmetic ingredients such as Liposomes, ceramides and sphingolipid.
Liposomes are microscopic beads that may contain water, vitamins or other nutrients. Because the structure of these elements is similar to the structure of cell membranes, they are easily absorbed by the skin. Liposomes can penetrate deeply into the skin with cells and releasing the substances contained therein.
Ceramides and sphingolipid-elements, fastening skin cells and prevent external influence, allowing you to retain moisture in the skin. Lipids with age disappear and water barrier is weakened. Studies have shown that the use of ceramides promotes the development of ceramides skin, which increases the lipid content and enhances the protective barrier.
When choosing a moisturizer look for these ingredients-they help to keep the beauty and youth of your skin.
