Cosmetic products invariably contain active additives - vitamins, amino acids, and minerals. Due to their exposed skin improves its appearance, smooth and velvety. But the production of cosmetics can not do without the use of other ingredients which allow assets to deteriorate long time and save your presentation. And not always the cream containing similar components, useful and safe for the face.
Beauty means perfect appearance and, above all, smooth smooth skin. For a long time the skin is considered a reliable defense against bacteria and viruses that are always present in the environment. It was assumed that if there is no damage on the skin, or ulcers scratches, no infection through it can not penetrate.
However, recent scientific studies show that it is not so. It turned out that the permeability of the skin of different people are different. Moreover, it can vary in one and the same individual at different stages of life.
Recipes cosmetics: what's inside?
Cosmetics for many years been based on this theory, a reliable protective barrier which is the skin. And various cosmetic company when creating their creams and serums are actively used substances that could be unsafe for the human body. Until recently it was thought that through the skin these components will not be able to penetrate. Today, many experts question the reliability of such "armor."
Some components required for production cosmetic products , Contain amines - technical additives such as emulsifiers. Furthermore, they may be present in the nitro compound (e.g., a preservative 2-bromo-2-nitropropane-1, 3-diol, one of the most common). If the formulation is used immediately in the one and the other, may form new compounds - nitrosamines.
For a man nitrosamines are considered safe. However, recent scientific experiments have shown that some of them can cause cancer in animals. For carcinogenic properties have been identified in diethanolamine (DEA). However, businesses do not use nearly DHEA in pure form, but its derivatives are included in cosmetic products often.
Other compounds from among the nitrosamines - triethanolamine - is now also checked for carcinogenicity: scientists suspect that this component may not be safe for humans. Another substance that has been subjected to harsh criticism - dioxane.
Make no preservatives
Prakticheskki any cosmetic product, whether cream or shade, is a very favorable environment for the development of bacteria. To harmful microorganisms can not live in the same jar of cream in his formulation is preservative. But it happens that the defense does not work, and as a result of using this cream skin suffering from infectious lesions, up to heavy and require long treatment.
That cosmetics did not cause harm to health, it should be closely monitored after the date of its release. If the period of use specified in the instructions, came to an end, even from your favorite cream must be disposed of without regret.
Keep cosmetics in the refrigerator rather than in the bathroom - it is warm and moist environment is conducive to proliferation of microflora.
Cream of jars just need to get clean, thoroughly washed hands. After this jar should be immediately sealed. And it is better never to use makeup mom or closest friends.
Cosmetic Safety Equipment
Among the ingredients listed on the labels of cosmetic products, you can often find SAW - surfactants, useful components to help quickly to get inside. Contains a surfactant, for example, in laundry detergents - shampoos, liquid soaps, shower gels. As well as in some cosmetic emulsions.
Some experts believe that the surfactant does not always bring only benefits, and cosmetics, which consists of such substances should be used not for everyone. According to scientists, surfactants disrupt the protective function of the skin, making it more permeable, not only for nutrients, but also for harmful microorganisms. Furthermore, some of the surfactants (e.g. widely used by manufacturers of cosmetics sodium lauryl sulfate) can cause irritation to people with sensitive skin.
It is necessary to use caution and cosmetic products and a high concentration alkali or acid pH. Their frequent use is able to make the skin extremely sensitive to any stimuli. In severe cases, it may develop neurogenic inflammation, when the skin will respond allergic reactions and dermatoses for all - from any piece of food to stress. For skin care and make-up did not turn health problems, carefully read the labels and choose the products of companies that have a long and proven track record in the cosmetic market.
