Cosmetics and immunity
Summer is associated with the sun and health. Autumn, on the contrary,
for many people is associated with the season of rains and diseases. So it is time to think about how reliably we are protected
against countless numbers of invisible viruses and bacteria, soaring in air or accumulating on doorhandles, banisters, handcarts
and telephone receivers.
There are two main ways of penetrating microorganisms into our body. First of all these
are mucous membranes of nasal and oral cavities and then - damaged skin areas. In some cases even an intact skin becomes involuntary
accomplice of microorganisms as many bacteria and viruses at first are settled on hand skin and then get into oral cavity.
Fortunately, nature has
provided for the possibility of microorganisms attack and have placedon their way highly effective barriers. In particular,
the skin is a well armed bulwark, able to prevent penetration of microorganisms into the body and actively struggle with them.
First of all, an emulsion,
containing secrets of sebaceous and sweat glands, is formed on the skin surface. It has acid reaction, unacceptable for the
majority of pathogens (pH 4.7-5.5). This acidic reaction is created, mainly, by lactic acid. Besides, there are bactericidal
substances of various nature, located on skin surface and its horny layer. And, at last, there are microorganisms on the skin
surface which not only adopt itself to live in acid medium, but do their bit in its creation, secreting organic acids.
The following barrier on
the way of microorganisms is horny layer. It is a layer of keratinized scales with lipid stratum between them. This barrier
is, practically, impermeable for water and microorganisms. When epidermal barrier is disturbed (damage of horny layer as a
whole or destruction of lipid stratum) microorganisms are getting in deep layers of epidermis. The easier water penetrates
through horny layer the more favourable conditions for microorganisms reproduction. There are two protective immune systems
against microorganisms - specific and nonspecific. Specific immune system works on the principle as memorizing and recognizing.
That is when a pathogen penetrates into the skin for the first time, immune cells memorize it and organize themselves to fight
against it. In case the same pathogen penetrates into the skin for the second time, immune cells immediately recognize the
disturber and do it away quickly and effectively.
Nonspecific immune system stirs to activity already at the first
penetration of a pathogen into the skin. For this purpose there are so called "watch" cells which are the first
to react to the presence of a "stranger". These cells give the alarm and the cells, able to destroy and swallow
up pathogens, immediately push on to render help. Besides, there are processes in skin that immediately start up, leading
to division of young cells of epidermis, restoring of horny layer protective barrier and synthesis of new antimicrobial components.
Owing to the multilayer
protective system the skin is so perfect barrier that pathogens on its surface do not do harm to the body. And what is more,
they are not able even to be there for a long time as in most cases they perish because of high acidity or because of influence
of natural antimicrobial substances or in the process of competition with own skin bacteria. But in case the skin barrier
system is disturbed, microorganisms penetrate through horny layer. At this stage it is quite possible development of inflammation
and allergic reactions with subsequent skin damage. And in such a case immune cells get the hang of things.
the better protective systems, preventing penetration of microorganisms into skin or destroying them before they have time
to activate specific immunity, the lesser risk that microorganisms will cause undesirable reactions.
Is there any possibility
in any way to help the skin in this struggle?
Really, there is a number of cosmetic ingredients which are able to strengthen the skin protective
properties. First of all, there are ingredients, strengthening antimicrobial properties of skin acidic mantle. Among them
are lactic acid and bactericidal and antiviral plant substances.
There are also cosmetic products, containing probiotics
frozen-dried lactobacillae. Besides, there are plants, possessing ability to stimulate nonspecific skin immunity. As a rule
these plants contain polysaccharides, activating Langerhans cells, having patrol functions in case of a disturber appearance.
Cellular processes of Langerhans cells are coming very close to the skin surface and this means that it is possible to influence
upon them by various cosmetic products.
The following ingredients belong to immunostimulators:
– contains galactoarabeenan – immunostimulating polysaccharide and also phenol compounds, acting as an antiinflammatory agents. The following Magiray products contain echinacea: Active Alpha Serum,
Active Alpha Cream, Fast Action local care - Day+Night.

Cream, Ultrasoftening Foot Balm.
contains bromelain – an immunostimulating enzyme. The following Magiray product contains pineapple extract: Natural
Buttermilk – contains
immunostimulating peptides and growth factor.
Yeast extract –
contains beta-glucan – an immunostimulating polysaccharide.
– contains fucoidanes – immunostimulating and antiinflammatory polysaccharides. The following Magiray products contain algae: Pear mask, Facial Toner for Normal to Dry Skin, Facial
Toner for Oily Skin, Hexa-cream, Triple Clarifying Complex (TCC), CLC Wrinkle Away Face Cream Plantain Lifting Gel, Essential

Indispensable Fatty Acids
– material for prostaglandine synthesis –
hormone like regulators of immune system. The following
Magiray products contain indispensable fatty acids: Replenishing Cream, Triple Clarifying Complex - TCC, CLC Skin Renovation
Moisturizer, CLC Wrinkle Away Cream, CLC Eye contour serum & mask, Hexa-Cream.
containing natural bactericidal and immunostimulating substances, considerably increase the skin protective ability, lessen
the risk of microorganisms penetration and prevent development of inflammatory processes. Stimulators of nonspecific immunity
are also useful in cases of skin damage as they fasten regenerative processes without any inflammatory reaction. Natural
immunomodulators possess also the ability to stimulate the processes of skin renovation and collagen synthesis, raising
the skin elasticity and removing facial lines.
