This is news! Although the smell of sunscreen immediately takes us to the sea, we probably wouldn't mind if we could apply it just once and then for good. In the journal Science Report, they reveal that a sunscreen with DNA could become the best and above all lifelong protection against dangerous UV rays.
Research in the USA have shown that it is in flight In 2015, only 14.3 percent of men and 29.9 percent of women used the cream, if they were exposed to sunlight for longer than one hour. Guy German from New York's Binghamton University says that “UV rays tan our skin beautifully, but they are carcinogenic". Dermoepidemiologists conclude that skin cancer is caused by UV rays because they damage the DNA in our cells, but German and his colleagues look at the problem from a different angle. In the research they used DNA from salmon seed, from which they made an extremely thin layer of film. The structure was then exposed UVA and UVB rays and tried to check how many of these rays the film lets through. To the surprise (or not!) of the scientists The DNA film did not let through as much as 90 percent of UVB and 20 percent of UVA rays. As a result, the DNA structure of the film improved further during the process.
Either way, it will take some time before the findings can be translated into our lives, but the outlook is good. Until then, let's take care of our skin according to already known guidelines.
