Creams and other products designed to protect skin from harmful UV rays of the sun are those creams who filter UV rays when is applied to the skin.
They absorb some UV rays in order to protect the skin and prevent burns or conditions caused by sun exposure, such as melanoma.
It is very important to protect your skin from UV rays, especially if you have a skin colored or sensitive. However, there are some dangers associated with the use of sunlight filtering role.Chemical Problems
Some types of role sunscreen products contain chemicals that can be harmful to the body. These are the ones that include octyl dimethyl PABA (OD-PABA), benzophenone-3 (BP-3), Homosalate (homometil salicylate, HMS), octyl-methoxycinnamate (OMC), and 4-methyl-benzylidene camphor (4-MBC ).
Biochemists say that these ingredients that are found in cosmetics, sun protection can act like estrogen and can give rise to confunzii through chemical messages in the body.
Other researchers argue that some sunscreen chemicals are actually toxic to humans. It is believed that PABA, dioxobenzonul, oxibenzonul and titanium dioxide – all commonly found in sunscreens and lip balms – may actually be carcinogenic.
However, it is very important to understand that these statements have not been tested enough and many sunscreen products can be used safely. If however you are concerned about certain chemical reaction of this kind, consult your doctor.
Vitamin D deficiency
Vitamin D is a very important chemical compound for humans. This contributes to maintaining the stability of calcium and phosphorus levels in the blood, helps calcium absorption and protects against osteoporosis and hypertension.
Some studies have shown that vitamin D may provide protection for certain types of cancer and autoimmune diseases. Vitamin D can be assimilated from various types of food and vitamin supplements, but it is most easily absorbed by exposure to UV rays. Sunscreens prevent absorbed adequate levels of vitamin D.
Some people with sensitive skin who have allergies or asthma, may react negatively additives in products that offer protection against UV rays. In some cases of asthma, perfumes can be irritating. If you suffer from asthma, opt for creams that contain no dyes, fragrances and preservatives.
In some studies it has been shown that there are enough people who excessively use UV-block products, without taking into account other sun protection methods (such as clothing or avoiding such spending time outdoors in the middle day when the sun’s rays are strongest).
However, sunscreen creams role, even if they can give people a sense of protection is insufficient, especially for people who spend long hours in the sun, do not use products with SPF applied properly or not often enough as should be.
You can not, however, determine a clear relationship between the incidence of melanoma and the use of sun protection, but this is still being investigated.
