BEAUTY WITHOUT DAMAGE TO HEALTH

 

 

So, where is the way out of this no-win situation? What should we do and how should we take care of ourselves? How to preserve beauty without losing health?

 

Beauty Secret dry cosmetics manufactured by LN-Cosmetics Research and Production Laboratory contains no synthetic ingredients such as parabens, sodium lauryl sulfate, etc. Beauty Secret products are based on lithocomplexes and mineral-and-salt compositions which, when used as key ingredients, do not mask the defects of our skin, but restore its natural, native features and properties, and regulate the functions of skin as an independent and one of the most important organs of the human body.

Skin is a vital organ of the human body.

 

The science dealing with skin has greatly developed over the last decade. Skin is the largest barrier organ in the human body; with an area of 1.5-2 m2, it protects us from negative environmental impacts,radiation, with bacteria and viruses, with mineral salts and insoluble particles. Every environmental factor produces a corresponding skin reaction; however, its defenses have their limits. Immune response is closely related to migration of leukocytes and regulation of skin structural proteins exchange. Human skin is a multilayered organ. The upper visible skin layer is called epidermis, its thickness comprises just one tenth of a millimeter, and its condition depends completely on the performance of the deeper, dermal, skin layer of approximately two millimeter thickness. The outer surface of epidermis is made up of a very dense layer, stratum corneum, which comprises scales representing the remainders of epidermic cells. On the average, for every 100 epidermal cells there is one immune cell (Langerhans cell) akin to the cells of thymus gland. Langerhans cells are responsible for skin immune response, including protection from bacteria and viruses, and occurrence of different allergic reactions. The next layer is called dermis (inner skin) made up of thick connective tissue comprising a network of collagen and elastic fibers, blood capillaries, lymphatic vessels, nervous and pigment cells, sebaceous and sweat glands, as well as hair follicles.

Dermis condition is determined by collagen, a fibrillar protein, which is the main structural element of connective tissue (comprising 72% of the dermis dry weight). When collagen is constantly renewing and retains water well, dermis maintains its normal thickness. As a result, such skin is elastic, and epidermis receives a good nutrition, which provides active cell division and a fresh and healthy appearance of the skin.

 

The deepest skin layer is represented bysubcutaneous fat. Subcutaneous fat can vary in thickness in different parts of our body. It consists of loose connective tissue having free spaces filled with fat lobules. This layer protects us from bruises, acts as a 'bed' for internal parts of our body, and provides skin mobility. To maintain an active state of skin, it is necessary that epidermal and dermal cells receive sufficient amount of nutrients, divide properly and synthesize structural proteins and polysaccharides, such as hyaluronic acid. Moreover, it is necessary to ensure adequate exfoliation of keratinized skin cells: if this function is impaired, skin becomes rough and dull. 

 

However, horny layer peeling should be performed very carefully in order not to damage a tender lipid barrier, which protects skin from moisture evaporation. The better stratum corneum can retain moisture, the younger look the skin has.

Solicitous attitude toward skin is essential, as its top layers contain numerous external (peripheral) immune protection cells. According to the recent studies by Russian and foreign researchers, elderly people have impaired feedback mechanisms between the skin and the immune system organs, which is indicated by inability to engage T-cells (8) in protective functions. Such defects can be reverted completely; we can make skin produce the missing signals again to attract T-cells using complex microparticles for this purpose.

 

Cosmetics is an art of beautification. All kinds of beauty products are primarily designed to improve our looks, i.e. to hide the defects of the outermost skin layer, the epidermis, including improving its color, smoothing out skin roughness and maintaining its elasticity. Yet, since epidermis condition and appearance depends fully on underlying causes, such as nourishment, blood supply, cell renewal, high quality cosmetics must first of all maintain natural functions of skin rather than amend its appearance. To keep our skin looking young, we need some means capable of helping in renewal of all the skin structures. For example, normally epidermis is completely renewed every three weeks, therefore, its cells should divide and its outermost corneous layer should exfoliate on a regular basis. If a beauty product hinders these processes, it actually works against you.

 

It is known that white lead and antimony salts were used for face makeup not that long ago, 

and those are highly toxic substances. Nowadays many beauty products contain definitely hazardous ingredients as well, which is unfortunately not reported on their labels. For example, all sunblock creams with high values of sun protection factor (SPF) (more than SPF 25) contain very toxic synthetic sunscreens.

The key skin care method is its cleansing. Proper skin hygiene is important to maintain a normal physiological state of skin, as its surface is being constantly contaminated by accumulating dirt and dust which precipitate on our body from the air, by dead cells of the epidermal corneous layer, by secretory products produced by sebaceous and sweat glands, as well as by many other skin contaminants. To enhance the skin excretory function, it is necessary to wash the whole body on a regular basis; it will help sebaceous and sweat glands to work properly and will keep your body nice and clean. To maintain its beauty, our body needs as much attention as our face does. It is known that every day human skin releases through sweat glands about 0.5 liter of water at room temperature, and up to 10-12 liters under the conditions of high temperature combined with physical work. Body perspiration, i.e. sweating, is the primary route of thermoregulation; sweat contains various metabolites, biologically active and toxic substances such as: protein degradation products, acetone, bile pigments, sodium and calcium salts. These metabolites should be removed from the skin surface, as they can be used as nutritive medium by pathogenic germs which cause inflammation.

 

Clean skin provides a better body protection from sun radiation and bacteria, and also helps to maintain a constant body temperature more effectively. On the other hand, contaminated skin cannot manage the mentioned tasks, which makes its owner suffer from excessive heat, infection or intoxication. However, it should be noted that some personal hygiene products, when used often for washing, can destroy corneal layer; therefore, when establishing washing schedule and selecting cleaning agents, individual skin characteristics should be always taken into account. Usage of various synthetic ingredients in cosmetics, cleaning agents and personal care products formulations increases negative burden on the whole body rather than just on skin, and many cosmetic procedures damage stratum corneum, increasing the risk of toxic substance penetration into dermis and then further into the blood stream. Systematic deterioration of skin structure leads to its dehydration and premature aging.

 

Skin age signs

What initiates skin aging? Obviously, water loss! It is known that aging skin has low moisture content, gets too thin, which results in wrinkle formation.

Skin age is the result of cell malnutrition, together with decrease in the ability of cells to divide and to synthesize large molecules under the influence of environmental factors, particularly UV radiation. Both epidermis and dermis get thinner with age, and skin looses its density and elasticity. Most of visible age-related changes occur in deep skin layers: less new collagen molecules are formed in dermis, and 'aged' collagen forms accumulate which have a poor water retention capacity. In the meantime, increase in metalloproteinase enzyme activity can be observed which leads to decomposition of collagen, elastin, structural glycoproteins and hyaluronic acid. As a result, skin is loosing its elasticity, wrinkles are forming and face contours are changing. Skin thinning is often accompanied by changes in pigment cells, or melanocytes. These cells become larger and increase in number, which leads to formation of pigmented spots. Furthermore, haemosiderin and lipofuscin pigments can accumulate in the skin intercellular space and in epithelial cells as a consequence of metabolic disorders.

Disturbances in intercellular exchange of signaling molecules of growth factors and cytokines are taking place, in consequence of which skin injuries require more time to heal, while the skin regenerative capacity is decreasing. Skin aging starts as early as at the age of 25, which is most noticeable on face and hands, while wrong choice of cosmetics can speed up this process even more.

 

Skin has the following functions:

·       provides thermoregulation;

·       protects from mechanical injuries;

·       prevents dehydration;

·       resists microbial ingress;

·       protects from ultraviolet radiation;

·       excretes waste products and toxins out of the body.

Contemporary science states that skin is an immunocompetent organ which acts as a partition between the body internal and external environment. It does not merely protect our body, but also interacts with the external environment: with thermal and ultraviolet
