In 1929, Coco Chanel French fashion designer imposes brown skin as a model of beauty and health. Gradually, and to present the exposed parts of the skin surface are being greatest if not in its entirety.

Likewise, and in order to maintain as long as possible dark appearance is made more prolonged sun exposure during hours of most intense radiation.

Lately they have proliferated a large number of artificial solar facilities and outdoor sporting activities persist virtually all times of the year for many social sectors.

This abuse and excessive exposure to sunlight has led to an increase in diseases, especially tumor, skin, a fact that dermatologists have already detected many years and therefore been warning about the consequences of excessive sun in the skin.

It is clear that the Sun is necessary for life as a beneficial influence in many aspects, heat, light, circadian biorhythms, physiological phenomena neuroendocrine disturbances in the psychic sphere seasonal pattern, formation of the provitamin D, photosynthesis of chlorophyll in the plants, etc., of which we can not ignore, even as treatment of certain skin diseases. It is also a source of energy that the industry takes to transform it into heat or electricity. But all this does not indicate that this radiation is used in an inappropriate manner for the sole purpose of being tanned. On this page we discuss, in a concise, comprehensible, all that should be considered on solar radiation and skin.

The color of the skin in Caucasian ethnicity (white) is given mainly by the proportion of melanin. The degree of pigmentation of the skin must be distinguished from basal pigmentation, ie, the parts covered and without prior exposure to the sun, and pigmentation gained by the action of light. The basal pigmentation is a constitutional and genetic trait. This has helped establish a classification of four types according to their degree of skin pigmentation.

TYPE I
Skinned, burn easily and are not pigmented

TYPE II
White skins, they burn easily and are pigmented little

TYPE III
Moderately pigmented skins, they burn quite easily but take some degree of pigmentation

TYPE IV
Brown skin. It is difficult to burn

Sunscreens are for topical preparations containing substances that partially or completely block light radiation. They appeared in the 1940s for photoprotection of American soldiers in the Pacific during World War II, since then its use has spread universally.

They are classified into two groups: partial or total chemical and or physical. The degree of protection from attempts to quantify a filter through so-called sun protection factor (SPF), or simply more protection index (PI). It is expressed with a numeric index ranging from 4 to maximum of 35 or more.

The SPF means the ratio of mean dose obtained in erythema skin covered with the filter and the average dose of the same skin erythema without protection measures both in the laboratory with the same light source and the same focus-skin distance. In a medium dose skin erythema which is 20 minutes if you apply a filter SPF 10 increases its resistance to 200 minutes.

A solar filter must meet the following conditions must be sufficiently adherent to the skin to resist once the moisture from perspiration and immersion in water should be safe and cosmetically acceptable and must express your FPS in the container, valued even by separately for UVB and UVA.

Sunscreens are essential today, but must take care that their use is correct to reject the idea that by using a protective filter can stay many hours in the sun. The SPF number indicates it is not always accurate, sometimes falling below the theoretical. Users tend to apply them in smaller quantities without properly extend through the skin in quantity and size. Should apply not only sufficient but also a uniform and consistent across the surface of exposed skin. Frequency of application will be after every dive even though the filter presumed to be resistant to water and regularly if for professional or sporting imperative need to stay longer under the sun exposure. It should use a sunscreen suitable for every skin type. For fair skin and for children is recommended SPF 35 or higher, in brown skin can be enough FPS between 20 and 25.

Ultimately the best photoprotection is once recognized the characteristics of the skin, not to abuse the exposure time even using sunscreen.

There are two major types of melanin, eumelanin, black, which is the most important and pheomelanin, reddish. Eumelanin, which is the melanin in his prime, has its maximum absorption spectrum at 300 nm, functioning as an effective filter radiation below this wavelength. The pheomelanin, is present in significant proportions in individuals redheads and filter effect is insignificant.

There are still third melanin, neuromelanin, located in some deep structures of the central nervous system, such as the substantia nigra or locus niger. Its composition and metabolism are not yet well known, this intriguing presence of melanin in anatomic areas completely inaccessible to light us to think that the melanin in the skin, and its filter function, must have other physiological mission. It has been suggested its possible role in neutralizing free radicals.

Despite these natural filters, continue to enter a certain proportion of UVB to the dermis. The UVA filters are insensitive to those transmitted through the epidermis, reaching deeper into the dermis. They have even greater penetration in the spectrum of visible light and infrared rays.

With regard to the absorption spectrum eye lens goes from 297 at 365 nm. Taken together, the anterior chamber filtered radiation below 400 nm, which is just the beginning of the visible light spectrum. Therefore radiation below it, both UVB and UVA, could have a role in the production of cataracts.
