(60) Two years later, a second group of researchers found that the licorice constituent glycyrrhizin "might offer protection from the damage induced in humans by UVB radiation." (61)
Conclusion: UVB radiation could cause increased 5hmC and TET expression, which might become a novel biomarker in UVB-related skin aging.
UVA and UVB radiation enhance Nrf2-responsive expression of genes encoding catalase, superoxide dismutase, and antiapoptotic proteins in dermal fibroblasts [5].

It has been revealed that PTEN plays a key function for DNA repair and viability following DNA-damaging UVB radiation [16].
Skin wrinkle formation was measured in hairless mice chronically exposed to UVB radiation for 8 weeks.
Lower ozone values can cause some overestimation of UVB radiation, but as the main factors influencing UV (SZA and cloudiness) have a much larger influence and variation, this difference is not decisive, especially considering that day-to-day variations of ozone can also be larger.
As long as you're in a green, yellow, or red area--in other words, pretty much anywhere on the map--your body will easily make vitamin D when uncovered skin is exposed to the sun's UVB radiation in June.

Whilst the SPF rating measures the level of preventing sunburn from UVB radiation and the upper limit is 50+, the PA rating measures not only the level sunburn prevention from UVA radiation but also the level of preventing wrinkles and sag.
Ozone absorbs UVB radiation, so holes in the ozone layer could be a pollution problem that winds up enhancing vitamin D levels.
Various tests revealed the good photostability and a UVA-to-UVB ratio even greater than 0.90, which means that the production has proved to be a comparable protection against both UVA and UVB radiation.
