Washington D.C. [USA], Nov 25 (ANI): The application of sunscreen on your body can & # 39; be good for your skin but of its nanoparticles may also affect your skin badly.
A new study led by researchers at the University & # 39; Queensland University & # 39; South Australia provides the first direct evidence that nanoparticles of & # 39; the zinc oxide used in sunscreen neither penetrate the skin and even cause cell toxicity following repeated applications.
The research, published in the Journal & # 39; Investigative Dermatology, rejecting claims widespread and growing belief among consumers about the safety of & # 39; Sunscreen candles based on nanopartikulati.
The researchers said the myth toxicity against sunscreen replaced after & # 39; previous studies on animals have found much higher absorption of skin & # 39; Sunscreen candle containing zinc than in human studies.
"There was concern that these nanoparticles of & # 39; the zinc oxide may be absorbed in epidermis, b & # 39; toxic effects, including DNA damage," said Michael Roberts, a leading researcher.
Link toxicity was collected from consumers, and warned fears that people can reduce their use of & # 39; sunscreen, repeated by National Survey on Protection of the Sun of the Council of Cancer 2017 shows a decrease in the number of & # 39; people who believed it was safe to use sunscreen daily.
Roberts and his co-researchers studied the safety & # 39; & # 39 repeated applications; nanoparticles of & # 39; the zinc oxide applied to five volunteers & # 39; between 20 and 30 years. The volunteers applied the ZnO nanoparticles per hour for six hours at & # 39; five consecutive days.
Using & # 39; & # 39 superior methods; images, the researchers established that nanoparticles remained within the superficial layers of the skin and caused no cellular damage.
"We hope these findings help to improve consumer confidence in & # 39; these products and in turn lead to better protection from the sun. The terrible consequences of skin cancer and damage the skin caused by sun exposure for long are far greater than any toxicity arising from the approved protection from sun, "said Roberts.
