Sun screen provides less protection than thought, say researchers. It is an established fact that people do not benefit from the ultra violet rays blocking advantage of the sunscreen as they are applying a very thin coat of the lotion than told by the manufacturers.
In a predominant experiment of its kind the King’s group appraised the DNA injury to the skin after modulating sunscreen spreading density below 2 mg/cm2, the amount producers use to attain their SPF rating.
Outcomes portrayed that the sunscreen with sun protection factor (SPF) of 50 smeared in the usual way would provide 40 percent of the presumed protection. The discoveries have engendered the King’s team to propose that consumers are making use of SPF sunscreen than they contemplate is required, to protect them from Sun’s harmful rays.
Scientists as their part of research divided 16 white skinned volunteers in two groups of eight (three women and five men in each). One group accepted a single UVR subjection to replicate sunlight, to areas cured with high SPF sunscreen of different thickness in the gamut of 0.75mg, through 1.3mg up to 2mg/cm2.
The other team underwent submission five consecutive days to impersonate regular holiday exhibition. The extent of UVR exposure differed during the direction of the experiment so that it could reproduce the state in holiday destination such as Tenerife, Florida and Brazil.
Biopsies of the UVR revealed areas of skin showcased that the group that were continuously exhibited to UVR substantial DNA damage was discovered on the areas encountered no sun protection even though the dose was very less.
