High-factor sunscreen shown to substantially cut melanoma risk

16 September 2016

A new study has demonstrated the potentially significant melanoma prevention benefits that high-factor sunscreen can provide.

Researchers from the University of Oslo analysed data generated by 140,000 Norwegian women over an average period of ten years, showing that using high-factor sunscreen can decrease the risk of melanoma by 33 percent compared with low-factor sunscreen.

Overall, non-sunscreen users had a lower risk of developing melanoma than those who used low-factor sunscreen, a trend explained by the fact that sunscreen users generally experienced more sunburn, took more sunbathing vacations and used sunbeds more often than those who never used sunscreen.

Reza Ghiasvand, a PhD candidate at the University of Oslo's department of biostatistics, said: "The explanation for this paradox is that some people use sunscreen to prolong sun exposure and acquire suntan. Moreover, many people don't apply the proper amount of sunscreen, forget to reapply and [fail to] apply on all exposed areas."

Given that melanoma is the cancer with the strongest increase in incidence in the last decade, the correct use of sunscreen is now more important than ever before.
