Therefore you should not ignore sunscreen with poisonous claims – Siasat Daily

Washington D.C. [USA], November 25 (ANI): Using sunscreen in your body may be good for your skin, but its nanoparticles can also affect your skin.

A new study led by researchers from the University of Queensland and South Australia gives the first direct evidence that zinc oxide particles used in sunscreen do not penetrate the skin and do not cause cell toxicity after repeated applications.

The study in Journal of Investigative Dermatology denies a widespread controversy and consumer perceptions about the safety of nanoparticle based sunscreens.

Scientists reported that the myth of organoleptic toxins was retained when previous animal experiments were zinc-containing sunscreens much greater absorption of skin than in human studies.

"It is worrying that these zinc oxide particles could be absorbed into the epidermis, resulting in toxic consequences, including DNA damage," says leading researcher Michael Roberts.

Consumers have contacted toxicity, which raises fears that people can reduce their sunscreen production. This is due to the national sunscreen coverage of the Cancer Council in 2017, which shows that the number of people has fallen because it believed they would use daily sunblocks.

Roberts and his co-researchers investigated the safety of repeating zinc oxide particles used in five 20-30 year old volunteers. Vapons used ZnO nanoparticles every hour for six hours after five consecutive days.

By means of powerful imaging methods, scientists found that nanoparticles remained skin-like layers and did not cause cell changes.

"We hope these observations will help to improve consumer confidence in these products and in turn to improve sunscreen. The horrific consequences of skin cancer and the long-term exposure to skin damage caused by skin are much greater than any of the toxicities caused by approved sunscreens," Roberts said.
