Cosmetology, in fact, practically does not lag behind the science and develops at a fast pace. However, in most cases, cosmetology offers are nothing significant that could really help women in the struggle with aging.
Consider, for example, a cream with liposomes, which has been actively promoted in the cosmetics market for a long time. This cream does not know what a shortage of buyers. Let's try to figure out how justified their choice and whether they caught on the next bait of marketers.
Is the choice justified?
The assortment of products with liposomes has already significantly expanded. Cosmetic companies produce not only gels and creams, but also sol-gel milk, various hair conditioners, women's perfumes and masculine lines - lotions with liposomes before and after shaving.
How not to dare to buy, when advertising from TV screens says that microscopic sizes of liposomes, easily penetrate into the deepest layers of the epidermis, delivering all the nutrients and moisturizers right into the center of the cell, giving elasticity and vitality.
In themselves, liposomes are empty capsules that perform a transport role and are filled with biologically active substances easily soluble in water.
Due to the possibilities of production, any chemicals-hormones, antiseptics, moisturizing complexes, vitamins and "anti-aging" enzymes can be placed inside the liposomes.
Initially, liposomes were made to protect drugs so that they do not collapse under the influence of external factors, during delivery at various injections, to internal organs through the blood.
In medicine, liposomes began to be used from one thousand nine hundred and seventy-one years. It took only some ten years, and they began to be interested in such giants of cosmetology, as Loreal and Christian Dior, who in turn started the development of a whole line of funds, which included the presence of the taxonomy.
Effects of liposomes and their possible in cosmetology
Liposomes by themselves do not represent anything of value. The main thing that is required of them is the presence of a void inside that allows you to hide in itself unstable compounds that are protected from external factors.
Researchers placed their hopes on the inner empty space of liposomes, which is reliably protected by a solid membrane from the influence of factors from outside. Liposomes should ideally be suitable for carriers of non-resistant compounds. In addition, everything was much simpler, since the structure of the shell and the structure of the cell membrane is very close to the structure of the membrane and the liposome, due to which the liposome particle was simply built into the wall cells.
It is known that enzymes are destroyed immediately, even in the upper layer of the epidermis, if they are not firmly associated with the carriers. And a cream on which the beautiful letters say "Q10!" the expected smoothing effect, the developers will not bring.
The same applies to vitamin E, one of the most powerful antioxidants, which has an excellent anti-aging effect due to the neutralization of free radicals, which in turn are the primary cause of the cell aging process. Under the action of oxygen, vitamin E is oxidized instantly. So during the application to the skimmed cream, which contains vitamin E, its vitamin saturation changes.
Such a universal carrier was searched by many for several hundred years, but the search at that time was not successful. The single substances were chemically inert, others did not have the most pleasant smell, which could not be suppressed even by the strongest odors, the third substances immediately evaporated at the slightest contact with air.
Hope remained only on the liposomes and the fact that their plasticity is enough to penetrate the deepest layers of the epidermis. Whether the cream with liposomes, hopes of buyers and manufacturers justifies?
Mythical action by a liposome
Thanks to modern production technologies, it became possible to obtain particles up to 0.1 microns in size. But usually the standard size of liposomes is from 0.2 to 0.6 microns. Try to remember this number. Intact skin has a pore size of 0.019 micron. It begs a completely logical question - and how, actually liposomes, which are larger in size, can penetrate into the skin? How fairly large is the liposome, can the shiny and horny layers of the epidermis pass without obstruction?
Developers who produce cosmetic means with liposomes, believe that this is due to some deformation of the very structure of the liposome while it passes through the microcapillaries.
It turns out an interesting observation. Twisting and deforming, the particle penetrates exactly where it is needed. But so far this has not been confirmed by a single official source.
The barrier of our skin can easily overcome a small number of liposomes.
Some creams were studied under an electron microscope. Studies have shown that there are no liposomes at all, or they have strongly disintegrated, that they do not show any desired effect, or have completely merged into a single mass.
This mass may well have an impact on the skin, but it is also scanty that one should not trust advertising. The same effect is produced by a conventional emulsion or gel-like cream.
It remains to assume only one. Liposomes get into our skin, only greatly crushed, but the internal contents remain untouched, what the manufacturers actually counted on.
Penetrate the preparation of the skin with lecithins, which refer to surface active substances. They are present in the egg-yolk. Therefore, drugs that contain yolk, not worse than advertised, may even be better, because their price is much less.
And one more thing. There is a theory that during the aging of skin cells their cell membrane thickens, and liposomes can repair these cells. However, no one could prove it. Old cells have the same membrane thickness as new ones.
It remains to ask - what then to restore?
