Today, almost everyone talks about the harmfulness of sunlight. 😎 But how come? What is the harm of sun if it is recommended to breathe fresh air at sea and catch some sun at the beach at least 14 days, or preferably all 21 ?! Sunlight is also involved in the production of melanin and vitamin D.”But what exactly is harmful about the sun?” “How can you safely rest and get a beautiful even tan without harm to the body, skin and hair?” “What UVA, UVB and UVC rays should I worry about?”
There are 3 types of sunlight:
❣👉UVC very short range of waves is filtered out even when passing through the atmosphere of the earth, and therefore we are not in danger. We can definitely cross it out on our list in “rays to worry about.”
❣👉UVB medium range ultraviolet radiation is scattered to a greater extent when reaching the earth’s surface, including clouds, and also retain the window (as opposed to UVA rays). Despite this, we reserve the list of “to worry” – from them we get a sunburn, and the kind of waves can cause abnormal development of cells, namely, a mutation that can lead to skin cancer.
Ethylhexyl Methoxycinnamate (octyl methoxycinnamate), Methylene Bis-Benzotriazolyl Tetramethylbutylphenol, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Phenylbenzimidazole Sulfonic Acid provide UVB filter and is designated as SPF (Sun Protection Factor). Such filters are called chemical – they absorb solar radiation, thanks to its structure. They penetrate the skin and from the inside absorb harmful rays.
❣👉UVA long range ultraviolet light that reaches 95% of the land surface, and that should be considered in any climatic zone and under any weather conditions. This type of rays involved in the “creation” of sunburn on the skin, but not only – their penetration into the skin deep enough, so these rays are considered among the most dangerous. They are the source of the formation of free radicals and are the cause of photoaging.We emphasize that neither clouds nor winter are protected from UVA rays, so the cream with SPF from UVA should be used not only in the summer in the period of visible solar activity, but also in winter!
