How the cosmetics protects from the sun?Summer holiday and a bright sunlight are inseparable. But the sun is artful, slightly stood gaping - not to avoid troubles. Its most dangerous “weapon“ - the ultra-violet radiation from which it is necessary to be able to be protected. In the market it is full of the cosmetics preserving skin against burning beams. To choose optimum, it is necessary to understand them well. the Modern cosmetics offers
two main methods of protection of skin against sunlight. Each of them is based on use of these or those chemical components. One protective structures physically block ultra-violet radiation and do not pass it to skin, others - filter it, partially absorbing and transforming solar radiation to less harmful form.
Among well-known protective ingredients of chemical filters - avobenzon, gomosalat, oktisalat, oksibenzon. Pluses of this class - a variety of chemical forms, simplicity of drawing and reliability of a protective layer.
At the same time some of chemical filters connect with possible allergic reactions and even with more serious diseases. It is connected with ability of their components to get into a blood-groove and to keep in an organism rather long time, about several days.
Nevertheless the American academy of dermatology recognized oksibenzon which most often causes complaints, harmless to children is more senior than half a year and adults at concentration of substance to 6%. In Europe concentration of 10% is considered safe.
Physical blockers, or physical filters, do not pass ultraviolet rays and contain such substances as zinc and dioxide of the titan.
Ingredients of blockers well protect from the sun and practically do not cause any irritations that is the most valuable to sensitive skin and to children. But with the cosmetic party there are small problems. Dioxide of the titan and zinc are capable to leave the cretaceous rest on skin, to decolour it and clothes.
How to learn to what class sunblock cream belongs? It is enough to look at its structure. If there zinc and dioxide of the titan is specified, it means a physical blocker of radiation if is not present - in a jar or a tube the chemical filter. It is necessary to remember, however, that some producers, seeking to strengthen protection, use at the same time both ways.
It is considered that efficiency of protection is influenced not only by a chemical composition of means, but also a way of its “delivery“. Choosing a form of release of protection against the sun, are guided only by individual preferences and reactions of an organism.
Liquid creams from the sun are “respected“ for their usability and universality. Liquid forms presented both chemical filters, and physical blockers and their mixes.
Among variety of structures there are special formulas for the person. They differ in the fact that in the list of their ingredients there are no fat oils or substances capable to litter a time.
Convenience of sun-protection sprays is shown when it is necessary to put protection in hard-to-reach spots or “to process“ fast before an exit to fresh air of fidgets - children.
Unlike fluids and sprays, sun-protection powders are less widespread. But their indisputable advantage - a possibility of use “on a make-up“ (from powder to it any harm) and “on the run“, literally in any place. “To powder a nose“ - what can be more natural to the lady, isn`t it?
Finally - about SPF. Its value is specified practically on all sun-protection structures. SPF as “sun protection factor“ is deciphered that means a factor of protection against the sun in translation from English. Strictly speaking, the uniform technique of its calculation was not thought up yet therefore producers can define it in the different ways. For consumers to know the most important that the SPF value is higher, the better protects cream from artful beams.
Good luck are also beautiful!
