The sun’s rays are a powerful form of energy.
They’re responsible for the rise and fall of Earth’s temperatures, and they’re the source of the most intense and damaging ultraviolet radiation that hits the skin.
But in recent years, the amount of ultraviolet radiation emitted from the sun has decreased and researchers are beginning to wonder if we’re actually seeing less of it.
Auto-policing sunscreens are now being tested to protect people from UVB and IR rays.
In a study published in Environmental Science and Technology, scientists at the University of California, Berkeley, found that using auto-protective film (APS) to protect the skin against the sun’s ultraviolet radiation was less effective than sunscreen on its own.
The researchers used a spray that was sprayed on the skin at different concentrations over a 24-hour period.
They found that the spray was more effective at preventing UVB than a combination of sunscreen and sunscreen-like products that contained zinc oxide.
Researchers concluded that the combination of zinc oxide with the spray “produced similar effects to a conventional sunscreen.”
The researchers also found that if you put the spray directly on the sunburn area and sprayed it to the skin, the combination “produced no visible changes in skin pigmentation, which was not significant after 24 hours.”
The research was published in the Journal of Applied Toxicology.
