This single ingredient helps filter out sunburn-causing UVB, as well as dermis penetrating UVA radiation, both of which can lead to an increase in the risk of skin cancer, according to the company.
Researchers believe the increase in left-sided skin cancers may be from exposure to UVA radiation while driving.
Since the intensity of incoming UVA radiation does not follow a spatial trend, the observed spatial variability may be associated with atmospheric changes, such as decreased cloud cover (promoting increased UVA) or air pollution events (dust storms, wildfires), that promote the scattering of solar radiation by particles (and thus reduced UVA exposures).
For almost a century the prevailing public health message when it comes to sunshine is it is bad, with UVA radiation penetrating your skin and creating DNA-damaging badness, while UVB will burn you, more directly messing your genetic material and promoting skin cancer.
ORDINARY glass absorbs 97% of the UVB rays that cause sunburn and some skin cancers - but only 37% of UVA radiation, responsible for ageing.
