We all want to look young and attractive, it is a natural desire of women. Unfortunately, not everything depends on the care, as you know, our appearance, skin and hair, slim figure is largely determined by the levels of female sex hormones - estrogen.
Over the years, their synthesis is reduced to maintain a decent appearance is becoming increasingly difficult. It would seem that once their estrogen is not enough, why not turn to outside help? Hormonal pills, hormonal ointments, cosmetics hormone - unless they can not correct the situation and to prolong youth face and body?
To some extent, yes, but the fee is sometimes too great. Weight contraindications serious side effects do not allow wide use of hormonal drugs for cosmetic purposes - only for medical reasons and under the supervision of a physician. And to add to the mass application of creams natural or synthetic estrogens are forbidden by law in virtually all countries of the world.
- Substances derived from plants and having a structure similar to that of estrogen, but devoid of the qualities that a concern when using female hormones.
Phytoestrogens and plant hormones - are two big differences
Hormones phytoestrogens are not, but the receptor (the specific protein structure) of the body respond to them about the same as in their native hormones, that is activated by starting the synthesis and regeneration processes of cells, including collagen and hyaluronic acid.
But there are plants and their hormones are botanically called - "plant hormones". These are auxins, gibberellins, cytokinins and other groups of chemicals that control plant growth and development. All these substances are no estrogen have no effect, so that no medicine or in cosmetics for the purpose of estrogen replacement do not apply. Typically, and in promotional materials and in various publications on cosmetic threads, the term "plant hormones" is used, referring to the plant hormones are not true, and the substance with a structure similar to estrogen. Such is the confusion of ideas has occurred ...
Phytoestrogens - where they are and how they work
Phytoestrogens - a substance extracted from plants, which in its action can mimic human estrogen, but only in certain concentrations and under certain conditions.
Phytoestrogens are almost all plants, especially a lot of them representatives of the plant world as soybeans, ginseng, red clover, alfalfa, flax, licorice, hops and red grapes.
Initially only attributed to phytoestrogens, sterols, which are part of the vegetable fat. Since their chemical structure they resemble human estrogen, theoretically, through activation of specific receptors on the surface of human cells, can induce the formation of collagen and fibronectin. In principle, in the laboratory, and they are. That's just to start this process, they need a huge concentration of 5,000 or more times more than the concentration of our native estrogen. So if you will just lubricate the skin soybean oil, or add oil in the cream, then, of course, the use of the skin of this will be, but not at the expense of estrogenic properties.
The desired effect can be achieved by using special techniques to extract additional steroidal phytoestrogens from the oil at the desired concentration, and place them in the cosmetic. Cosmetics manufacturers who decide to use such a complex and not a cheap process in modern conditions, and is certainly not cheap. Typically, cosmetic companies are introduced in the composition of their products, or extracts of plant oils. Phytoestrogens it undoubtedly is, but that's the extent of their concentration raises serious doubts in the effectiveness of such funds.
Furthermore sterols to phytoestrogens include, and phenolic compounds hydrophilic nature namely flavones, flavonones, isoflavones, chalcones and others. These substances are found in abundance in the plant tissue, but just as in the case of sterols, their concentration in the extracts is far from necessary to exhibit estrogenic effect. It requires special treatment and methods of concentration. Companies that own such technologies, evaluate their products very cheap.
For example, "Firming gel cream with isoflavones (phytoestrogens) for mature skin» (Essential Shock Gel-Cream) by Natura Bisse (Spain). The composition of this medium, together with numerous other useful components include
Isolated from extracts of soybean root and Florentine iris. The cream can be recommended as a good anti-aging agents to effectively counter age-related changes in mature skin. True, the manufacturer as well as all others, does not mention at what concentrations of isoflavones are included in the cream.
Well, most often in the jar with a cosmetic product can be found in a number of other components "phytoestrogens" and what and in what concentrations - guess yourself. Most likely, no estrogenic effects of most of these funds do not have, but to say that they are useless, you can not!
Apart from estrogens, phytoestrogens, including isoflavones possess excellent antioxidant properties, humectants firming effect on the skin and moisture-system. As a result of the use of cosmetics containing phytoestrogens, skin becomes smoother, looks younger and healthier, even if their estrogenic effects and is not shown in full. Furthermore, plant extracts and oils also contain other useful components: fatty acids and fruit acids, vitamins, minerals and trace elements.
Which is better: to smear or eat?
Many phytoestrogens are widely used as pharmaceuticals and as food additives. It turns out that the oral route, they are able to influence many aspects of our health, though highly positive: to strengthen the heart, improve immunity, prevent cancer, help to strengthen the skeletal system, improve skin condition.
For example, soybeans
. Major soy isoflavones - genistein, daidzein and glycitin
. In most non-fermented soya products (soya milk, tofu), they are present as glycosides (genistin, daidzin and glycitin)
. Under the action of intestinal microflora glycosides are converted to the active form of genistein and daidzein, and then their metabolites (ekvuol), these active isoflavones have weak estrogenic and antiestrogenic effect depending upon the level of estrogen in the body
. That is, when it is necessary (in the body of a little estrogen), they act as substitutes (solving many of the problems associated with a lack of hormones), and when estrogen excess, the isoflavones, competing with them for the receptors, thereby reducing total estrogen load on the body preventing the development of many hormone-dependent diseases
. In addition, it is proved that soy phytoestrogens have antioxidant properties, a beneficial effect on bone mineral density and protect against bone loss, prevent cardiovascular disease
If you are not sure about the organic quality of soy products and are experiencing concerns about genetically modified soybeans, pay attention to the source of phytoestrogens such as flax.
Shell flax seed - the richest vegetable source of great representatives of phenolic phytoestrogens - lignans. Lignans from food in our body, under the influence of specific intestinal microflora podvergayutya bioconversion and moving into the active form. By the way, if you use them externally, no estrogenic effect, they do not have. The use of the same products that contain lignans, inside allows to normalize by replacing estrogen hormones. Modern methods of extraction of lignans allowed to create food products (flax meal) enriched by these phytoestrogens. It has been proven that in addition to estrogenic lignans have anti-viral, anti-bacterial and anti-fungal properties that are powerful antioxidants and immune modulators.
Properties of phytoestrogens has not been studied until the end, we are only at the beginning, but also doctors and cosmetologists are confident in the prospects of huge curative, preventive, health and beauty products with a phytoestrogen.
