Comment on Why can't I apply SPF50 sunscreen twice to get SPF100 protection?
SaveTheTuaHawk@lemmy.ca 2 weeks agoThat’s a massive reduction and on top of that skin cancer is the world’s easiest treatable cancer with the lowest death rate.
Unless it goes metastatic then the death rate is very high.
Sunblock is not about preventing sunburn, DNA gets damaged far before sunburn. I suggest you get better information, because you clearly don’t understand this.

DNA doesn’t just start getting damaged before the sunburn. It’s instantly from the first millisecond you’re out in the sun. However it’s surprisingly not a linear relationship where 60 minutes or sun carries twice the risk of 30 minutes of sun. The heavy inflammation associated with a sunburn has a cancer risk of itself, independent from the actual UV dose. So while minimizing UV is important, it may be just as important, if not more important, to make sure you are never sunburned. I can provide sources if asked
